LUMINOSITY AND CREATING GLOWING COLOR.

TRANSPARENCY OCCURS BETWEEN PAINT PARTICLES.

Many people say that the way to create a “glow” in watercolor is to paint pale glazes of “luminous,” transparent hues so that the white of the paper underneath passes through the paint particles “like light through a stained glass window.” Apparently, however, light passing THROUGH a layer of watercolors is not the way luminosity actually works! That description is just a myth! 

According to several color scientists, chemists, and Bruce MacEvoy (handprint.com), little light actually passes THROUGH the particles. Instead, transparency happens when light reflects off the paper BETWEEN the particles of watercolor paint.

We know that watercolors don’t form a solid paint layer the way acrylic and oil paints do, as discussed in this post: ‘Some Watercolor Pigments Lighten More Than Others When They Dry…,’ (9/7/2022), https://leemuirhaman.com/2022/09/07/some-watercolor-pigments-lighten-more-than-others-when-they-dry/ . Oil and acrylic paints stay on top of the painting surface and dry in a solid paint layer. 

In contrast, watercolors (made up of various sizes of suspended paint particles ) end up “on top of, between, and underneath paper fibers” (Bruce MacEvoy of handprint.com). More of the white paper is therefore revealed as the water evaporates. The most transparent of watercolor paints produce a thinner coating of smaller pigment particles on the paper. These pigments in a smaller particle size seem to hide less of the paper (or other pigment particles) underneath, making the color appear more transparent. Thus, transparency happens BETWEEN these pigment particles and NOT THROUGH them ( see http://www.handprint.com/HP/WCL/tech16.html) .

ACHIEVING THE GLOW OF LIGHT.

Although transparency and glow may not work the way we once thought, achieving a glow remains a goal for many artists. We want to paint the light! We wish to highlight brightness, glow, radiance, luminosity. But to create a luminous glow, don’t rely on using lots of ‘bright’ colors that may not work together. Bright colors can be intense but also may be dull and opaque, and they may not set each other off to advantage. For example, yellow is a bright color, but if applied too thickly, even a transparent yellow becomes LESS luminous and will no longer be a light value. 

‘Golden River Sunset’ Watercolor Painting.

Instead, although transparency is essential, luminosity comes from choosing colors by their effect on each other; that is, you should choose colors that create a reaction with nearby colors. Remember that paint colors change their apparent brightness, transparency, and hue depending on the context in which they appear. 

To bring about a glow, you will want to create CONTRAST in both VALUE and TEMPERATURE by surrounding a transparent light color with a COMPLEMENTARY dark ( a dark leaning toward the complement of the light color, NOT an unexciting, flat tube black such as Ivory Black, or purchased mixes such as Payne’s Gray or Neutral Tint). Colorful darks can therefore enhance the effect of light in a painting. The function of a dark color is NOT JUST to create value contrast, but to help the light-valued color (whether warm or cool, muted or intense) to glow. (For more information on complementary colors, review ‘The Color Wheel, Color Bias, And Color Mixing In Watercolor’, (7/2/2019), https://leemuirhaman.com/2019/07/02/the-color-wheel-color-bias-and-color-mixing-in-watercolor/ .)

HOW? VALUE CONTRASTS AND COLOR COMPLEMENTS.

What painting methods actually work to create glowing color? First, choose a pure, transparent color, well diluted to a light value. Second, mix your dark surrounding values to be complementary dark colors. If your light value is a pale yellow, you might try to use a version of deep purple or dark purple-gray. 

‘River Flowing Forward’ Watercolor Painting.

ADD COLOR AND TEMPERATURE COMPLEMENTS.

To further exaggerate the glow that is forming, you can adjust your dark by taking into account color temperature. That is, establish a warm-cool relationship between your light and dark by remixing your complementary dark, altering proportions of pigments to move the color to be cooler or warmer. If your light valued yellow is WARM, the best complementary dark to set it off would be a COOL bluish-purple dark. Or for a COOL light valued yellow, contrast it with a WARM, reddish-purple dark. Always judge a color in relation to the colors next to it. A blue, for instance, will feel even cooler next to a warm color.

‘Rocky Maine Shoreline Sunset’ Watercolor Painting.

TRY MID-VALUE CONTRASTS ALONG WITH COLOR AND TEMPERATURE COMPLEMENTS.

At times, a strong dark can overpower your composition. In such a situation, a mid-valued color contrast can also enhance and complement the glow of light values in the painting. Mix the complement of your light color, shifting it into a warm or cool variation, as needed, to create a temperature contrast. But instead of a rich dark, strive for a mid-value mix. If you mute this mid-value mix somewhat by adding a bit of its complement, you will gray the mixture, thus setting off the light-valued color. A cool purple (which you gray slightly with a touch of warm yellow) will cause your warm yellow light to glow even brighter. In the same way, you can gray a warm red-purple with a bit of its cool yellow complement to make a cool yellow light look still brighter.

‘White Primroses’ Watercolor Painting.

OR CREATE AN ILLUSION WITH UNTOUCHED PAPER.

Perhaps you want to leave the untouched white paper as your light value. It’s possible to make this white begin to glow depending on what you choose for a nearby accent. Whatever mid-tone you pick creates a subtle, optical or color illusion as it nudges the white paper into appearing as a complement. There is actually no need to alter the white paper, even though that might be your first tendency. Cool nearby colors will make the unpainted paper seem warm. For example, cool blues create a subtle orange glow, while cool purples move the nearby whites toward a yellowish glow. In this way, you can establish a glowing contrast, instead of merely a simple dark-light contrast.

(Much of the above information on how to create glow through complementary darks and dulled mid-valued colors is presented in  Jeanne Dobie’s Making Color Sing: Practical Lessons on Color And Design.) 

‘Clouds Over Dales’ Watercolor Painting.

IN SUMMARY.

The mechanism producing “glow” may be different from what people say, but you as a painter don’t need to DO anything differently as a consequence of your new understanding of how that mechanism works. You can create the illusion of glow in a watercolor painting in several ways. 

Remember that paint colors change apparent brightness, transparency, or hue depending on the colors that are nearby. Therefore, you can establish luminosity by building color relationships (through value and temperature) between lights and darks (or mid-values). 

Try to use transparent, single-pigment paints to maintain the impression of light. Opaque paints are thicker and duller, and can become lifeless in mixtures, causing you to lose ‘the light.” Also avoid using lots of bright colors hoping that ‘brightness’ (without contrast) will create luminosity.

Learn to use complementary colors to create color and temperature interactions that produce glow. Your goal when mixing luminous color is to combine unequal proportions of the two paints in a mix, so that the final color is either warm or cool and can be used to complement another in value, as well as color and temperature.

Some Watercolor Pigments Lighten More Than Others When They Dry…

Don’t settle for less vibrant color in your watercolor painting. I see too many watercolor painters whose paintings could be improved by using stronger mixes of paint in their art. A watercolor painting needs contrast, strong lights and darks, to create impact (unless, of course, you’re painting fog, mist, or similar types of weather).

Make your colors vibrant! (EerieLight Watercolor Painting).

Watercolor paints change their color appearance as they dry. Colors that look to be the right value and color when painted and wet, may shift as they dry, creating a ‘DRYING SHIFT.’ Expect almost all watercolor paints to appear paler, duller, and less bright when they dry. 

DRYING SHIFTS VARY BY PIGMENT.

However, when drying, some pigments change appearance very little whereas others change a great deal. Not only does a watercolor pigment end up looking different from what you expected when you mixed the paint, but EACH PIGMENT changes to a varying degree compared to other pigments. 

Test Your Colors To Overcome Drying shift (Beach Shadows Watercolor Painting).

WHY DO WATERCOLORS LIGHTEN AS THEY DRY?

Oil and acrylic paints look much the same whether wet or dry, and stay on top of the painting surface as they dry, bonding with the paint binder and forming a paint layer. In watercolor painting, however, the combination of paint, water, and binder (whether gum arabic, glycerin, honey or a glucose humectant) behave differently (from oil or acrylic paint) as the water dries. 

According to Bruce MacEvoy of handprint.com, when watercolors dry, all of the water evaporates, and the paint vehicle (BINDER) “along with the dissolved surface SIZING of the paper,” are drawn by “capillary action” into the tiny spaces between the paper fibers, where they harden and dry. Paint particles may be a VARIETY OF SIZES and DO NOT uniformly stay on the surface of the paper. Instead, MacEvoy says, “in many watercolor paints, smaller pigment particles tend to be less saturated and lighter valued than the larger particles. These duller, paler and smaller particles also remain in liquid suspension longer than the more intense, darker and heavier particles, which sink first to the paper surface and into the paper crevices” where they are more hidden from light. No solid paint layer seems to be formed. Pigment particles are “strewn on top of, between, and underneath paper fibers,” revealing more of the white paper. Thus, watercolor paints will appear to whiten or fade as they dry. (http://www.handprint.com/HP/WCL/tech16.html , and http://www.handprint.com/HP/WCL/cds.html .)

CHANGES IN PAPER.

The PAPER SURFACE also changes during this process. (Different brands of paper, weight, fiber content — e.g., cellulose vs. cotton fibers — and paper finish — e.g., hot press, cold press, rough — will each be affected somewhat differently.) But, in all cases, the wet paper fibers soften and expand, becoming thicker and fuzzier, especially with repeated brushing of the paper or ‘fussing’ and fiddling with the applied paint. In general, the less agitation of paint on the paper, the better. Lots of brushing forces a larger number of pigment particles into the scuffed paper crevices which will DULL the color. If you want to achieve bright, clean color in your painting, try to apply your paint in one brushstroke (or in as few as possible) and let it dry. Limit your brush strokes!

Avoid Over-brushing (Red Bumpers Watercolor Painting).

COMPENSATE FOR DRYING SHIFT.

Drying shift is one reason color mixing can be very challenging in watercolor painting. As a watercolor artist, you should be aware of drying shift and know that you must compensate for it by adjusting your paint/water ratio. More specifically, get to know which paints on your palette tend to have a great drying shift and dry lighter or duller. (See http://www.handprint.com/HP/WCL/cds.html for Bruce MacEvoy’s chart of Watercolor Paint Drying Shifts where he lists the pigments he has found to have the greatest shifts. For example, Prussian Blue, Indanthrone Blue, Lamp and Ivory Blacks show some of the largest drying shifts, whereas Cerulean, Hansa Yellow Light, Cadmium Lemon, and Benzamida Yellow have low drying shifts. Keep in mind that drying shifts may vary by brand as well as pigment, since different manufacturing and milling methods will affect the size of paint particles.) 

With some notion of which of your watercolor paints produce greater drying shifts than others, you can compensate for this tendency by mixing those pigments with LESS WATER (decreasing dilution) to create a more vibrant color mix. It is always a good idea initially to test your mixed color on a watercolor paper test sheet prior to painting, let it dry, and check its appearance when dry. With experience, you will become able to judge what the pigment will look like in a painting when dry.

Intense color (Iris Watercolor Painting).

IN SUMMARY.

Color drying shifts in watercolor pigments are highly variable. These shifts depend on several factors:

  • the pigment itself (different pigments behave differently), 
  • brand/manufacturer of paint (various milling methods),  
  • paint vehicle (type of binder), 
  • paint dilution (some paints can be made more vibrant by mixing with less water), 
  • type of paper (brand, paper weight, fiber content, and finish), 
  • and application method (try to limit repeated brushing). 

Compensate for large drying shifts by adjusting water/paint ratios when mixing your paint. Use more pigment (or less water) in your color mixing to intensify a color likely to produce a large drying shift. Feel free to check your mix on a watercolor test sheet to ensure your dried color will be the correct value or the value that you intend. 

So, once again, don’t settle for less vibrant color in your watercolor painting!

Wow! Value, Hue, And Intensity!

Every color has three different components. These qualities are value (lightness or darkness), hue (the color name), and intensity (saturation or brightness). Each brushstroke in a watercolor painting is affected by all three aspects of color, although usually the properties are discussed and adjusted separately. By manipulating value, hue, and intensity in a painting, you will be able to create the illusion of space and three dimensions as well as create art filled with feeling.

COLOR VALUE.

I have heard it said that VALUE (a color’s lightness and darkness) is the most important of these three elements of color to get right in a painting. Value helps to create form and to show the direction of light. In order to better see value in a scene, squint your eyes. Squinting allows less light to reach your eyes and will reduce both the color (hue) and detail you see, making it much easier to isolate light and dark values. Even when squinting, you will probably see many values ranging from black through a range of dark to light grays to white. Trying to capture every one of these variations in paint, from dark to light, would be too overwhelming. It is best to simplify; narrow down the number of values you plan to capture, and limit yourself to 3-5 values for ease of painting. For example, limit your choice of values to darkest dark, lightest light, and one or two mid-tones.

One method of achieving the desired value of your color, is to mix the right amount of water with the right amount of paint. If you add more water to a watercolor mixture, you get a lighter value. If you instead add more pigment, you create a thicker, darker mix. The thickness of your color mix relates to its value.

Further, you can create the desired value of a color by first choosing the right pigment for the value you want. Catherine Gill, in Powerful Watercolor Landscapes, pp. 120-121, suggests, “If you want a light value, choose a transparent pigment. For a middle value, choose an opaque. For a dark value, choose a stain.” You still must adjust the amount of water you use. For a light color using a transparent pigment, use more water. For achieving middle value color, make a thicker mixture with an opaque color. An even thicker mixture made with a staining color will produce a dark value.

Values – Beach Shadows Watercolor Painting.

HUE.

HUE is the name used for a color. Red, yellow, and blue are hues. An almost infinite number of hue variations are possible, from yellow-green to turquoise to blue-violet. When we talk about hue, we are NOT referring to light or dark, bright or grayed, or strong or weak. To better understand how hues (colors) relate to each other, learn about the COLOR WHEEL. Each hue has its own specific placement on the color wheel, depending on its similarities and differences to other hues. 

B. MacEvoy Color Wheel. (Download your own copy https://www.handprint.com/HP/WCL/cwheel06.pdf)

Hues located close to each other on the color wheel have more similarities; they contain more of the same primary color than hues located farther from each other. Nearby hues are harmonious and analogous. In contrast, those hues located farther away from each other on the color wheel are less closely related. Two hues opposite each other on the color wheel have little in common; they are complements. If mixed together, complements create a neutral, grayed hue, whether gray or brown. When complements are painted side by side in your painting, they contrast strongly and can emphasize each other.

HUE AND TEMPERATURE.

COLOR TEMPERATURE, whether a color is warm or cool, is a characteristic of hue. Every color leans either toward warm or cool. On the color wheel, cool colors are grouped together (blue, green, violet). Warmer hues (red, orange, yellow) are located together on the opposite side of the color wheel. While yellow is generally a warm hue, some yellows are cooler than others. For instance, a Cadmium Lemon pigment is cooler (closer to blue on the color wheel) than warmer (more orange) Cadmium Yellow. Cadmium Red is warmer than Permanent Alizarin. And Sap Green is warmer than Hooker’s Green, which is warmer still than Viridian. Thus, even within a hue, you will find a variety of temperature differences. You can warm a hue by adding yellow and cool one by adding blue. 

A color can also appear warmer or cooler depending on the hues painted nearby. In other words, a color’s appearance is relative. You will want to judge a hue’s temperature in relation to colors next to it. Ultramarine Blue next to Cadmium Lemon will look cooler than the same Ultramarine Blue next to Cadmium Red.

Color temperature changes in a painting affect a picture in several ways. 1.) Color temperature can show the effect of light and shade. Warmer hues ( combined with a lighter value) can indicate the sunnier or brighter side of an object, while cooler hues suggest shadow and less light. Items closer to the sun are generally yellower and warmer than those farther from the sun or light source. Where the surface of a feature changes direction, you can alter color temperature and show its contours. For example, the east side of a barn may be in direct sunlight, but the north side may be in shadow; a contrast in color temperature can capture the three-dimensional quality of the image.

Changing color temperature to illustrate contour. – Barn Watercolor Painting.

The quality of light can also change color temperature. A sunset may transform everything to a rosy hue, whereas a road during a rainstorm may become grayish purple. Observe the light source BEFORE choosing your hues for a painting. You may notice a warm light source (a bright sunset or artificial lighting, which is often warmer than outdoor lighting) where you will need to paint cool shadows. Or the light source may be cool (from a north-facing window, outdoors under the blue sky, or even on an overcast gray day), suggesting the need for warmer shadows. So remember, shadows are NOT always cool.

2.) Color temperature can help you create depth in a painting by taking advantage of the fact that warmer hues tend to advance (pull forward) while cooler colors recede (push back) into the distance. With cool bluish, distant hills appearing farther back than warm foreground fields, you can create space in a painting. (As the distant hills recede, they will also tend to get paler, less intense, and will display less contrast and softer edges.)

3.) Colors (hues) can have a psychological effect on mood. Color contrast can add energy to your painting. Warm colors like red, yellow, and orange tend to arouse emotions such as love, passion, happiness, hunger, and anger. In contrast, cool colors, such as blue, green, and purple are thought to bring calmness, sadness, or indifference. Red sports uniforms have been linked to higher win rates. Blue has been linked to sadness, gray to feeling down, green with jealousy. You can use color temperature to engage your viewers, to get them excited or relaxed.

INTENSITY.

Color intensity is a color’s saturation, purity, or brightness. An intense color is pure, whereas a less intense color is grayed. Intense colors, like Phthalo Blue, Cadmium Red, or Ultramarine Blue, are found on the perimeter of the color wheel. Less saturated colors, such as Indigo, Sepia, or Venetian Red, will fall toward the interior of the color wheel. To lessen the intensity of a bright color, add some of its complement or a close complement (the colors opposite on the color wheel). For instance, to lessen the intensity of Hooker’s Green, you could add a slight amount of Cadmium Scarlet, Cadmium Red, or Permanent Alizarin. Some readily available (but less intense pigments) include Sap Green, Payne’s Gray, Indigo, Yellow Ochre, Burnt Sienna, Raw Umber.

Understanding color bias helps you mix high-intensity or low-intensity colors. A warm red pigment contains some yellow – it ‘leans’ toward and is biased toward yellow, whereas a cooler red would have more blue and would lean toward blue, or have a blue bias. A hint to help you create a bright, intense mixed color is to use two colors biased TOWARD each other on the color wheel (e.g., a yellow situated closer to the blues mixed with a blue situated closer to the yellows), thus avoiding the addition of any of the third primary color, red, which would gray the mixture.

The grayer, softer colors provide restful areas within your painting. Less intense, grayed colors can also be used to draw attention to and support a bright color (providing color contrast), allowing the bright to take center stage. Contrast in color intensity near your center of interest can help to emphasize it. On the other hand, too many bright intense colors will compete with each other and can easily overwhelm a picture. A range of intensities in a painting creates more interest and a better painting.

SUMMARY.

Use what you have learned here about value, hue, and intensity of color to improve your paintings and to paint strong three-dimensional pictures. Begin by considering value to begin to capture light and shadow. Then, work to create a range of warm and cool hues to establish mood and depth. Build more distance and interest while supporting your center of interest with grayed, less intense color.

APPENDIX A: TEN COLOR COMPONENT TIPS

1.) Squint your eyes to better distinguish value (light and dark).

2.) Simplify your composition, and reduce the number of your values to 3-5        

     for ease of painting.

3.) To mix a lighter value, add water to a mixture. To create darker values, 

     use less water and more pigment, making a thicker mixture. Mixing 

     color with a transparent paint is the easiest way to create a light value. 

     Opaque paints are ideal for mixing mid-tones, while staining paints 

     work well to mix dark values.

4.) Each hue has its own specific placement on the color wheel, depending 

     on its similarities and differences to other hues. Understand how the

     color wheel makes it easier to mix colors, to use warm and cool colors 

     effectively, to arrange your palette, and to find a color’s complement. 

5.) Every color leans either toward warm or cool. You can warm a hue by

     adding yellow and cool one by adding blue. 

6.) The appearance of colors can vary depending on which colors are 

     nearby. You will want to judge a hue’s qualities in relation to the colors 

     next to it. Understand also that the quality of light can change 

     color temperature, suggesting a possible call for reconsidering the 

     temperature of your chosen pigments for a picture. Warm light 

     suggests the need for cool shadows, while cool light creates warm 

     shadows.

7.) Use value and color temperature to suggest light and shade and to 

     create depth in a painting. 

8.) Understanding color bias helps you mix high-intensity or low-intensity 

     colors. You must take bias into account if you hope to create either a 

     bright or less intense color and hope to avoid a muddy color. A warm

     red contains some yellow – it ‘leans’ toward and is 

     biased toward yellow, whereas a cooler red would have more blue 

     and would ‘lean’ toward blue, or have a blue bias. 

9.) To insure a bright color mix, use two colors biased TOWARD each 

      other on the color wheel (e.g., a yellow situated closer to the blues 

      mixed with a blue situated closer to the yellows), thus avoiding the addition of any 

      of the third primary color, red, which would gray the mixture.

10.) Grays and less intense colors support and set off bright colors. 

       Include them in your work to provide more interest and an improved  

       painting. To dull or gray a color, add some of its complement. Gray 

       can also be mixed by combining all three primary colors (red, yellow, 

       and blue).

Let’s Get Shady!

Why are there such variations in the appearance of shade and shadows, even within a single picture? How, as artists, can we capture that variation with paint? Why do some shadows have hard edges and others appear soft? Why are some shadows darker than others? Read on…

Value.

We know that mastering light and shadow is key to successful watercolor painting. By using VALUE (light and dark) a painter can give an object shape, form, depth.  PATTERNS of light and shade are, in effect, what we are actually trying to capture in paint.

Light Source.

When beginning to paint, an artist needs to consider where the light is coming from, the LIGHT SOURCE. The way light hits an object affects how it is seen and how it will be painted. Are you painting a bright sunny day, a dark overcast day, or a gloomy interior, for example? Light affects mood, and will determine the types of shadows you need to paint. Beginning painters sometimes try to avoid painting shadows, but then wonder why their image looks flat and incomplete. Shadows create form – add shadows to a drawing of a circle and it becomes a rounded sphere. So, at the outset, analyze how and where the light strikes an object. (Keep in mind that there may even be more than one light source!)

 

Complexity!

Initially, shadows may look as if they are made up of only two values, light and dark. But look more carefully and you will see a much more complex reality.

Barn Interior

Shadow components.

Break down a shadow and you will find many components. The HIGHLIGHT is the area hit directly by the light source. There is often little or no detail visible here, as it is too bright. Paint a highlight with a very pale tone or leave the white of the paper.

The area of an object that is transitioning from the highlight to the darkest shadow area is called the HALFTONE. If the object is curved, as a sphere or rock, this transition of value is gradual, and would be painted with a soft edge.

The actual SHADOW (sometimes called a LOCAL or FORM shadow) will be in the area of the object that is hidden away from the light. It is generally the darkest area, receiving the least amount of light. Shadows are dark, but rarely black! To mix shadow color, you might mix the local color of the object with some transparent blue (sky light) and some of the local color’s complement.

Often, light can be reflected back into the shadow, illuminating it. This REFLECTED LIGHT bounces off a nearby surface and carries some of the color of that surface into the shadow. Reflected shadows would be lighter than the actual shadow, but never as bright as an area directly in the light. The amount of color reflected depends on the intensity of the light source as well as the character of the surface reflecting the light. Observe carefully how much reflected light you see in shadows and what colors are introduced there.

A CAST SHADOW is created by the object interrupting the light, and its shape relates to the shape of the object and the ANGLE of the light source. The cast shadow will follow the contour of what it falls on, for example, uneven ground. It will grow LIGHTER in value and softer-edged the farther it extends from the subject casting the shadow. The darker and harder-edged you paint cast shadows, the brighter the light will appear. Choose clear blue shadows for sunny days, whereas on overcast days, a cool gray or grayish purple would be a more appropriate choice for shadows. As the weather and quality of light in the sky changes, so do the color, value, and edge qualities of the cast shadows.

barn walshaw

 

Wet-in-wet is an ideal technique to introduce color into a still wet shadow. You might paint a base shadow wash in a lighter tone than your final desired value, then drop in additional colors, each successive color mixed to a somewhat drier consistency than the previous ones (to avoid over-wetting and creating pools of paint). Don’t overmix colors when you add them into a shadow, which would create a dull uniform gray that appears flat. You want to retain separate colors and variation of color within a shadow. Remember to use transparent colors in your shadows if your aim is to deepen and darken the shadow. On the other hand, bright opaque pigments, such as yellow ochre or raw umber, could lighten the shadow and suggest reflected light. You might also lift out patches of color to build lighter spots of dappled light, or reflected light.

Hard or soft?

Several factors affect the softness/hardness of shadow edges. We know the SOURCE of light changes the appearance of shadows. With a single bright light source, such as the sun, shadows will be strong and sharp. Diffuse light, on the other hand, such as through a window out of direct sunlight or on an overcast day, produces shadows less defined and with soft edges. In diffuse light, value contrasts will also be less strong.

Jamison's Ocean Light

So, sharp edges and details are found in well-lit areas, whereas soft or lost edges and ambiguity are located in the shadows. It doesn’t make sense, for instance, to try to paint sharp, crisp details in darkened, poorly lit room. Instead, blur or soften details in shadow, even painting shadowed areas wet-in-wet on dampened paper with a passage of mingled colors. (Remember to dampen as evenly as possible, however, to avoid puddles or pools of water. Don’t flood the area with lots of water. Pre-wetting evenly encourages a soft blend of paint.) Leave your paper dry where you want to retain details, perhaps under bright lamp light.

Also, the DISTANCE FROM THE OBJECT casting the shadow to the shadow itself also has an effect on whether shadows are hard or soft edged. Where the shadow lies close to the object, such as plants in a flowerpot casting a shadow on the ground, the shadow will tend to be crisp and dark. A tree, farther away from the ground, will cast a lighter, softer shadow, since as the distance increases, more light is able to reach the shadow.

Try to apply what you just learned in this blog post about shadows. Take a look at this Kenny Harris painting (below) and see if you can analyze and make sense of the many and varied shadows.

No Light Without Shadow!

\All painters want to know how to portray light in order to create atmospheric and dramatic effects. When an artist can emphasize light, an everyday scene can become far more exciting. Since light is represented in watercolor by the untouched paper, the light is already in the painting. The watercolor artist must preserve the white/light while painting mid-tones and shadows in order to accentuate the light. Only by painting the darks or shadows that surround the light can the light be made obvious.

Light on Hill

 

On a bright sunny day, very pale washes (or untouched white paper) suggest direct sunlight, for instance, while darker mixes of color indicate a more shadowed area. Be bold! Without darks, your lights will lack liveliness. Take a look at Paint Your Shadows Bold…And Transparent!, https://leemuirhaman.com/2019/01/29/dont-be-afraid-to-paint-your-shadows-dark/, my blog post from January 29, 2019, for more tips on painting shadows.

Value contrast (with lights close to and emphasized by darks) can create the illusion of light, depth, and a center of interest. On the other hand, if there are too many areas of equal light intensity (or a lack of shadows) in a painting, the image will tend to look flat, less interesting, or bland. If you tend to avoid painting dark colors, perhaps by adjusting your values you could create a picture with more impact.

In many ways, almost nothing is as important in a watercolor painting as how you handle lights and darks (value). (For more in depth information on value, read Why Should I Bother To Use A Gray Scale?, a blog post from May 21, 2019, https://leemuirhaman.com/2019/05/21/why-should-i-bother-to-use-a-gray-scale/.) Protecting the light areas is crucial, so try to plan what areas of the picture you want to save as light before the painting begins. While you can mask, scrape, scrub, or use opaque white gouache to save/regain the white of the paper, it is often much more successful to preserve the variations in light from the outset with a painting plan of attack.

By seeing light and learning to capture it with paint, we can create the dramatic illusion of light in our work. But as Jean Haines says on page 43 in Colour And Light In Watercolour, “Before we can even begin to paint light, we have to be able to see it. Once you start to look for light it becomes an addiction. No painting feels right without it. It becomes a part of your being as an artist. You find yourself searching for ways to bring light into your work, and even more ways to paint it.” So, think about where light plays a part in each of your paintings, and observe what it is about the light on your subject that grabs your attention.
