Why Does It Matter If My Paint Is Transparent Or Opaque…As Long As I Like The Color?

Knowing a paint’s attributes puts you a step ahead as an artist. By being familiar with whether a pigment is transparent or opaque, staining or non-staining, saturated or unsaturated, for instance, you will begin to be able to predict how the paint will behave. Understanding your pigments is an important step in getting the results you want and in being successful as a painter.

TRANSPARENT VS. OPAQUE:

A TRANSPARENT color maintains its luminosity or brightness because it allows the white of the watercolor paper to reflect back through the paint to the viewer’s eye. Since a transparent color lets light through, it is possible to create the illusion of a ‘glow’ of light in a painting.

In contrast, an OPAQUE watercolor pigment blocks the light and prevents luminosity. While thinning an opaque color can make it somewhat more transparent, it will then lose intensity (strength). In general, you cannot see the white of the paper through an opaque paint. The more opaque a color is, the more it blocks the white of the paper, particularly if it is layered.

STAINING VS. NON-STAINING TRANSPARENTS:

If you plan to glaze one color on top of another color to create optical color mixing, use transparent colors. If you want to create the effects of light and produce a ‘glow’, use a paled, transparent color.

Be aware that there are both STAINING and NON-STAINING transparent colors.

STAINING TRANSPARENT pigments, such as Indian yellow, Phthalo/Winsor Blue, Phthalo/Winsor Green, Prussian Blue/AntwerpBlue, Phthalo Violet, are bold and intense. They are NOT easily lifted. Because they are transparent, they will NOT produce mud IF mixed with other transparent  colors. Mixed full strength, they create rich darks.

NON-STAINING TRANSPARENT pigments, such as Permanent Rose, Aureolin Yellow, Viridian, or Cobalt Blue, on the other hand, are delicate and can be lifted easily. They are ideal for glazing, layering, or mixing a transparent gray from primary colors.

Still other pigments, like Lemon Yellow, Gamboge, Quinacridone Rose, Cobalt Violet, Sap Green, or Ultramarine Blue, are LOW-STAINING and transparent to semi-transparent. Intensity of these colors is average, and they can be partially lifted.

If you wish to lift one color of a mixture and reveal a second color underneath (e.g. by blotting out clouds or scraping paint back to create rock texture or a tree trunk), then combine a staining pigment with a non-staining pigment.

OPAQUE colors tend to be less bright, although semi-opaque pigments, such as Cadmium Red, Cadmium Orange, Cadmium Yellow, or Cadmium Lemon, can be somewhat luminous when thinned or diluted. The opaque earth colors, like Indian Red, Light Red, Yellow Ochre, Burnt Umber, Sepia, Indigo, or Cerulean Blue, are often LOW-STAINING and UNSATURATED (not a vivid bright). Burnt Sienna and Raw Sienna, earth colors, are a bit unusual in that they can be transparent. Remember that adding an opaque color to a paint mixture or layering with an opaque pigment will make creating ‘muddy’ color more likely. Further, if you begin a painting with opaque color, you’ll probably lose the effect of light.

CREATE A COLOR CHART TO DETERMINE TRANSPARENCY:

Transparency and opaqueness of paint pigments can vary quite a bit by manufacturer. For example, Raw Sienna ranges from yellow to orange to brown depending on the company that formulates it. So, get to know the specific paints YOU have on your palette by creating a color chart. First, draw a line with a black permanent marker (or waterproof India ink). Allow to dry. Paint swatches of medium dark paint over the black line. Transparent colors won’t cover the black line. Opaque colors will. Staining colors will look dark.

IN SUMMARY:

Most organic or synthetic paints are transparent, while earth colors tend to be semi-opaque or opaque. The transparent pigments are the most versatile type of watercolor. They remain transparent when mixed with other transparent colors. Opaque colors, on the other hand, DO NOT mix well with other opaques. Try to combine opaque paints only with a transparent color or colors, if possible, to avoid mixing muddy colors. Or, best of all, use an opaque pigment by itself to show off its best attributes.

Get to know the paints on your palette. As Jean Dobie states in Making Color Sing, “To paint glowing, vibrant watercolors, you must become familiar with your pigments’ personalities.”

Avoid Painting Lollipop Trees! (Part II.)

When you practice painting trees, begin by studying the bare outlines of winter trees (deciduous), because you can better see their whole structure and their proportions.  In general, the proportions of a tree can be divided into thirds: one third trunk, one third branches, one third twigs.  This principle may not always apply, but it gives you a helpful place to start.  Observe whether the tree exhibits a single vertical trunk or multiple trunks; a twisted and contorted trunk, possibly weeping branches, or angular or smooth-flowing branches.  Very few trees are symmetrical.

Use a round brush to paint the main trunk and thicker branches, then a rigger to paint thinner branches or twigs.  (A palette knife or liner can also be useful for painting small twigs.)  Alternatively and more simply, you can scumble in the smallest branches of a winter tree with a light tone to suggest the smallest growth.  For a winter tree, work from the bottom upwards.  Establish the trunk and main branches boldly; then begin to “suggest” a few smaller branches before rendering a light tone (by scumbling or dry brushing) for the fuzzy tiny twigs.

The complicated outlines of trees in leaf can be overwhelming without SIMPLIFICATION.  It is important to remember that the same basic structure as is there in winter still lies beneath the cloak of foliage.  You should paint the foliage as several large masses, varying them in size and making the shapes interesting, while also leaving rough edges; nevertheless, each should have three dimensions.  Some masses should overlap others, but leave gaps between some to form important sky holes.  Paint branches and twigs in these sky holes, NOT on top of the foliage shapes (Lost and Found).  You should not paint individual leaves.  Definitely do not paint detail you cannot see from a distance.

In general, when painting foliage, prepare a wash for the lighter areas and another, stronger wash for the darker spots.  (You have the option of using even more color layers to increase color and tone variations.)  If you apply the first light wash in a series of quick strokes with the side of your brush, the resulting shape will tend to look more spontaneous than overworked.  Then, before the first layer of color dries, drop in some of the darker wash to correspond to the darker, shaded areas you have observed.  You must remember to leave random sky holes.  For trees in leaf, begin your painting with the foliage; then add trunks and branches.  Tops of trees  (facing the light) will usually be the lightest areas.

How Does A Painting Progress?

The first step in a watercolor painting is usually choosing an image to paint.  Sometimes I am excited about a subject or intrigued with the way light affects a scene.  That image can make me feel a certain mood or remember a wonderful feeling I’ve had before in a similar setting.  Often, the scene “picks me”: it touches me, and I want to paint it.

The painting “Mulpus” began in this way.  When I saw the photos that my son had taken of a brook that we both know, I felt the excitement of discovering a magic secret garden in my backyard.  The series of photos taken on a clear spring day showed a progression from the old stone bridge on the road up the sparkling brook edged with bright green moss and grass to the ruins of a towering stone wall dam that in the 1700’s had controlled water for a log-cutting mill.  The dam, though still impressive, was partially collapsed and the mill pond gone, but, oh, the water sparkled, and the green of the moss and grass was brilliant!  How refreshing!  In the midst of decay was renewal.  I could almost feel the warm sun, see the rosy buds about to open, smell crisp, clean air, and hear the soft whisper of the breeze!

I settled on two reference photos to combine and sketched a template for transfer to watercolor paper.  When I had the image drawn, I used masking fluid to preserve the sparkles of white on the water, the bright green shore, and highlights of the rocks in the water.

When the masking fluid was dry, I pre-wet the sky and tree line area with clear water.  As the sheen disappeared, I painted the sky with a very pale wash of a mixture of mostly cerulean and some Winsor (or phthalo) blue.  I tried to leave the center of the sky area paler than the surrounding sky because I chose to have the sunlight shining from the center of the picture toward the viewer.

Keeping in mind a clear spring day, I mixed colors for the far tree line.  Spring green was a possibility, but these trees were in the background, and I did not want them to stand out or compete with the bright green grass and moss which would be the focal point of the picture (in conjunction with the sparkling water).  Therefore, I toned the green down a bit to a slightly-grayed blue-green mix of ultramarine blue, DaVinci sap green, and a small touch of burnt umber.  And since I wanted the distant trees to appear soft and unfocused, I painted the tree underlayer onto damp paper.  (If you mix this tree color at the same time as your sky mix, you’ll be ready to paint your tree line as soon as you finish the sky.  However, if you find your paper has dried out since you painted your sky, it’s perfectly fine to rewet your sky and tree line with clear water, then paint your tree line when the sheen has gone.)  While the tree line is still damp, scrape in a few trunk-like lines with a palette knife or brush handle.  (Some pale gray trunks can be added here later and softened.)  Also, while the distant tree area is still damp, randomly drop several other colors into the tree area to add variety.  For me, these colors were a touch green gold and separately also burnt umber (mixed with a touch of burnt sienna).  Don’t get carried away here – less is more.  Every tree you paint should have a variety of colors in it.  As these color additions started to dry, I used a slightly stronger version of the underlayer green (ultramarine blue, DaVinci sap green, and a touch of burnt umber) to scumble in and start to suggest shadowing and shaping of the tree line.

mulpus step 2.jpg

I began to work on the large stone wall by mixing three separate puddles of very, very pale color to apply as an underlayer.  I used permanent alizarin red (or quinacridone red), cobalt blue, and hansa yellow light (or cadmium lemon) to mix these three puddles.  These colors I randomly painted onto the stone wall; each color remained separate but just touched another of the three colors.

Mulpus step 3.jpg

 

While the stone wall dried, I began to put down the first layers on the middle distance tree trunks (which would eventually have more detail than the distant tree line).  I started with the trees to the far right to avoid spoiling the stone wall before it dried; then I gradually worked toward the left.  Since the type of tree, the age of the tree, and the smoothness of the bark cause variations in the tree trunk color, I used more than one paint color.  First, I laid down a pale greenish gray made with Davy’s gray.  Almost immediately, I began to add variation – some green gold and/or raw sienna on the sunny side of trunks, and darker brown-gray made of ultramarine blue with burnt umber on the shaded side.  I needed to remember the direction of LIGHT for shadows:  because I chose to have the light come toward the viewer from the middle of the picture, shadows on the trunks are on the right side of a trunk on the right of the picture, but shadows on the left side of the picture are on the left side of the trunks. I laid these colors in without mixing.

I painted one tree at a time so that the colors could soften into each other and create shape in the trunk before the applied paint had a chance to dry.  I let these underlayer colors in one trunk dry before proceeding to detail work on the trunk and moved instead to underlayer the next trunk.  When all the mid-distance trees were underlayered, I added details (crevices and knotholes) with a dark brown of ultramarine blue and burnt umber.  This same color I used to dry brush a bit of texture on the tree trunks, including grooves and shadows at the roots.

I then painted another layer of color, made from cerulean blue with a small touch of cadmium red to make a gray, over all of the large stone wall.  The color was not too dark, but pale enough to see hints of color through it.  When this was dry, I painted details in the wall – for example, crevices, shadows, texture – with a gray-black mixed from ultramarine blue and burnt umber.  I left light some highlights on the top of the wall, though I could also have lifted them later.

A light layer of burnt umber I laid over the earth area to the right and left of the stream.  I let this layer dry while I began to paint the water in the stream.

The water I painted wet-in-wet.  For this technique, it is best to have all the colors ready BEFORE starting to apply any paint.  To get ready, I mixed five separate puddles: cobalt blue; ultramarine blue; burnt sienna; ultramarine blue/DaVinci sap green/burnt umber; and ultramarine blue/burnt umber.  The first layer put down on the pre-wet paper was a layer of cobalt blue over all the water, avoiding the rocks.  Some of the green mix I dropped into the cobalt blue near the shore of the pool next to the ruined dam and close to both shores to suggest reflections from the distant tree line and the grass and moss along the shore.

Before the water dried, I added some burnt sienna in the water closest to the left front corner.  These transparent colors (cobalt blue and burnt sienna) made it seem that the viewer could see through the water to the sand on the streambed below.  Again, before the water dried, I darkened the edges of the water in particular with ultramarine blue.  Closest to the shore, where the bank overhangs a bit, I added some ultramarine blue/burnt umber mix (blue black) and made sure the color was softened as it met the rest of the water.

While the water was drying, I worked more on the forest floor.  With burnt umber and then with a dark brown/ burnt umber mix, I darkened the ground toward the far tree line on the right and up close to the large stone wall on the left, where the ground would be in shadow.  I added some texture and a few darker indentations in the fallen leaves with the dry brush technique.  I spattered the brown ground first with the dark brown mix, then with just burnt sienna. When the spatter had dried, I added a few strong tree shadows on the ground while keeping in mind the direction of the light.

The stones and rocks in the water received an underlayer of gray (cerulean blue and cadmium red).  When they were dry, I used the dry brush technique again to texture in the gray and dark gray I used previously, also adding dark shadows where the water meets the rocks.

When all the paint was dry, I removed the masking fluid.  Green gold was the color for the brilliant and sunlit moss and grass (though hansa yellow light mixed with ultramarine blue could also work).  The shadow color for painting depressions in the green ground came from adding more ultramarine blue to the above color.  In darker spots, I added burnt umber/ultramarine blue to increase depth.

Finally, to finish up, I added more tiny branches to the mid-distance trees.  I scraped (with an X-acto) some white water to make sure the stream looked natural.  I also lifted some rock highlights that seemed to have been lost.

Painting Skin Tones.

There are so many variations in skin tone that it seems overly simple to choose only certain specific pigments for painting skin.  In other words, you don’t have to use prepared color formulas.  Consider variables of age, ethnicity, light source, reflected light, and gender when you are painting skin color.  Skin color does NOT come in a tube; it must be mixed by the artist based on an interpretation of the colors seen.

To reproduce skin colors accurately, observe your subject closely.  Painting skin tone has more to do with the light and the environment than with any preconceived notion of what skin color should be.  You must analyze how and where the light source strikes the skin surface.  From which direction does the light come?  Is there more than one source of light?  Can you see any reflected light in the shadows?  What colors do the shadows add to the general skin color?  Is the light soft or harsh?  Warm or cool?  Brighter light will make reflected color stronger and more obvious.  Bright light darkens and sharpens shadows.

Skin color can vary from the palest yellow on through pinks, browns, and ebony.  Light skin tones appear transparent and vibrant.  Dark skin shows a range of rich, exciting colors.  Look for a subject’s general skin tone; then alter tone by diluting with water for highlights or by adding a complementary color to create shadows (for example, a trace of green shadow on a pink jawline and a bluish or purple shadow on brown or dark skin).

Facial areas like nose, ears, cheeks, chin, and tear ducts of the eyes tend to be warmer in color than the rest of the face.  The most basic way of painting skin is, after careful observation of general skin tone, to mix that color with two to three transparent paint colors.

Possible skin color combinations might be:

For fair skin—

Burnt Sienna/Cadmium Red/New Gamboge

Burnt Sienna/Permanent Alizarin Crimson/Cadmium Yellow

Burnt Sienna/Winsor Red/Cobalt Blue

For Native American or Hispanic skin –

Burnt Sienna/Brown Madder/Cobalt Blue

For Asian or fair skin –

Raw Sienna/Burnt Sienna/Cobalt Blue

For dark complexions –

Burnt Umber/Permanent Alizarin Crimson/Ultramarine Blue

Burnt Umber/Permanent Alizarin Crimson/Cobalt Blue

Burnt Sienna/Burnt Umber/Ultramarine Blue.

IMG_5846.jpg

Apply the general color thinly in a pale wash.  When this underlayer is dry, layer more color, as needed, to suggest skin depressions and create form.

Adjust the ratios of your colors to fit your subject’s skin color and value.

When trying to make the skin in your painting lifelike and interesting, you should paint wet-in-wet or on damp paper to allow for soft transitions.  In painting skin, your layers should follow and define the shadows you observe.  You must have value changes to imply form.  Build up your layers of paint, remembering to save areas for the highlights.  Create form and depth by painting depressions and shadows, leaving highlights created by lightly painted layers.

IMG_1618.jpg

More experienced painters might prefer to mix paint on their paper rather than premixing a general skin color on the palette.  When paint is mixed on the paper, colors are much more interesting and vibrant than the same color combinations mixed on the palette, then applied to paper, which tend to be dull.  Glazing and layering one color at a time on the paper gives skin a luminous tone.  Apply the lightest washes first; then gradually progress to the darkest washes, which you should apply last.  Build up transparent layers with Hansa Yellow Light, Permanent Rose, Quinacridone Gold, Quinacridone Magenta, Winsor Red, Winsor Blue (Green Shade), and Winsor Blue (Red Shade).

Be sure to use transparent colors for a clear, luminous effect.  By choosing a warm and a cool transparent color for your palette, you will have more than enough color options to produce unlimited skin tones.  By varying proportions of each color to change color temperature AND by paying attention to the order in which the colors are layered, you can create different skin tones.  (Remember that the last layer of color glazed on will determine the dominant hue of the skin.)
