In the early days, pigments for painting were rare! The specific ingredients and recipes for making paints were closely guarded secrets. These paints were made by hand from soils, minerals, animal matter, and other materials. The paint did not keep well and had to be made frequently from scratch.
Modern pigments, although still using some of the same ingredients, are manufactured from a wide variety of substances, often through complicated chemical processes. Many more different pigments are available to painters today, with an incredibly wide range of color choices. Because we now have so many colors to choose from, it is necessary to narrow down the options and simplify.
COLOR NAMES AND PIGMENT NUMBERS.
A painter can’t possibly use every tube color out there, and there is such overlap between brands and ‘named colors’ offered that it wouldn’t make sense to try every one. Be aware that the name given on each tube can be very deceptive! For instance, some ‘raw siennas’ are not really raw sienna at all, but are made from the yellow ochre pigment. A ‘sap green’ in one brand looks different and is made from very different ingredients than ‘sap green’ from another company. The color you think you’re buying is not necessarily what you get! Further, some paints offered are unreliable and fade when exposed to sunlight.
What’s to be done? READ LABELS (just like at the grocery store) to know what you’re getting and to get the best products. On tubes of watercolor pigment, look for the pigment LETTERS and NUMBERS printed on each tube to tell you what the paint is actually made from – companies often include this information in small print on the tube. The letters indicate the pigment hue (color); for example, PB means ‘pigment blue,’ and PR stands for ‘pigment red.’ The numbers that follow the letters are those assigned internationally for that pigment material; for example, a true viridian paint contains PG18 (or ‘pigment green number 18), not something else that might look like viridian.
Using pigment letters and numbers instead of just color names will help you learn to be more aware of what paints you are using. Gordon MacKenzie, in his book The Watercolorist’s Essential Notebook: Landscapes, goes into a lot of detail explaining which pigments to AVOID because of unreliability. Mr. MacKenzie also shares which brands have the BEST quality in which colors. (It is interesting that no one brand offers the best quality in every color they produce!)
In choosing colors for my watercolor palette, I tried to consider color characteristics. The FOUR characteristics of color to think about are: 1. HUE is the name of the pure simple color, e.g. blue, yellow, red. (Hue describes the pigment’s location on the color wheel.) 2. VALUE is a pigment’s lightness or darkness. 3. INTENSITY is the brilliance or saturation of a color. (A pigment can be dulled by adding its complementary color – the color opposite it on the color wheel – which in the right amount produces gray.) 4. TEMPERATURE is warmth or coolness of a color. Reds, oranges, yellows are said to be warm, while greens, blues, or violets are thought of as cool. A color or hue can ‘lean’ toward either the warm side or the cool side, and the direction it leans affects how it behaves during color mixing with another hue. In order to be able to mix pigments into a wider range of colors, try to choose both a warm and a cool version of the primary hues.
On the color wheel, colors are placed in position on the circle to indicate their degree of warmth or coolness and their relationships to each other. Color placement on the wheel can therefore suggest the degree of borrowing or leaning toward another color – a ‘warm’ red (like cadmium red) is closer to the yellows and also contains more yellow than a ‘cool’ red (permanent alizarin red) which would be closer (on the color wheel) to and contain more blue. You can follow the colors around the color wheel to see how much borrowed color is in each pigment.
It becomes easier to combine colors when you can visualize your pigments on the color wheel. For this reason, I decided to try the Stephen Quiller watercolor palette, which has wells for pigments arranged in a circle (color wheel) for ease of color mixing. (The Richeson Stephen Quiller watercolor palette is available on jerrysartarama.com for $22.99, as of the time of this writing.)
CHOOSING YOUR COLORS.
In many ways, choosing particular colors for your palette is a matter of personal preference. Yet, there are a few guidelines. Recently, I have been searching for more transparent watercolors to add to my palette. I find that having too many opaque colors in a painting can destroy the GLOW of light that I hope to get down on my paper. However, I wanted to keep a few opaque colors on the palette. Also, I tried to to include some brilliant, staining colors, as well as some fairly transparent earth pigments. Such a variety of colors allows for mixing a wider range of colors. My reevaluation of pigments seems to be an ongoing process, because just when I think I have finalized my color choices, I find another irresistible and useful hue!
MY COLORS…TODAY AT LEAST.
So, what colors do I have on my palette today? These are the 24 colors that I placed around the circle (with some exceptions to the color wheel theory just because I liked the colors): Hansa Yellow Light PY3 (Daniel Smith or DaVinci), Gamboge Hue PY153PY3 (Daler Rowney or DaVinci), Indian Yellow PY153 (Daniel Smith or DaVinci), Raw Sienna PBr7 (Daniel Smith or DaVinci), Light Red PR101 (Holbein), Indian Red PR101 (Holbein or Winsor Newton), Cadmium Red PR108 (DaVinci or Daniel Smith), Pyrrol Red (Daniel Smith) OR Winsor Red (Winsor Newton) [both are pigment PR254], Quinacridone Red PR206 (Daniel Smith), Quinacridone Pink PV42 (Daniel Smith), Quinacridone Violet PV19 (Daniel Smith or M. Graham), Mineral Violet PV15 (Holbein), Mauve PV19PB29 (DaVinci), Payne’s Gray PB15PBk6PV19 (Winsor Newton or Maimeri), Ultramarine Blue PB29 (Daniel Smith or DaVinci), Cobalt Blue PB28 (DaVinci), Phthalo Blue RED SHADE PB15 (Daniel Smith, DaVinci, or M. Graham) OR Winsor Blue RED SHADE PB15 (Winsor Newton), Cerulean Blue PB36 (Holbein or Winsor Newton), Blue Apatite Genuine (Daniel Smith), Phthalo Green BLUE SHADE PG7 (DaVinci or Daniel Smith) or Winsor Green BLUE SHADE (Winsor Newton), Viridian PG18 (DaVinci or Daniel Smith), Sap Green PG7PY42 (DaVinci!!!), Shadow Green PBk31 (Holbein) OR Perylene Green (Winsor Newton), and Rich Green Gold PY129 (Daniel Smith) OR Azo Green (M.

BASIC COLOR RECOMMENDATIONS.
I don’t recommend that beginning painters have all of the above mentioned colors on their palettes. Having fewer colors will help you begin to learn the characteristics of your colors and how they behave when used alone or when mixed with others. Being able to MIX the exact color you want to use in a painting is INVALUABLE! A basic beginning palette might include: Quinacridone red, Quinacridone Violet, Mauve, Indian Yellow, Hansa Yellow Light, Ultramarine Blue, Cobalt Blue, Phthalo Blue Red Shade, Viridian, Sap Green, Payne’s Gray, Burnt Sienna, Raw Sienna. When you become familiar with the basic colors, you can feel free to experiment and slowly add more colors. Enjoy! Color is fun!
For many years, I used the colors and brands of watercolor paint that my instructors used. (Interestingly, each instructor had different preferences.) There were so many different colors to choose from I was unsure why they used some colors and not others. I didn’t worry too much about their color choices when I was just starting to paint, being more focused on learning technique, but as I gained experience, I wanted to understand why we used those particular colors. Was it just a matter of personal preference, or were certain colors better for some reason? Why?
LEARNING ABOUT COLORS.
‘Color’ became more and more interesting to me. I became fascinated by how many different ways there were to mix colors from the paint that was already on my palette. There was such variety! Yet at some point, I began to feel some dissatisfaction with certain black, gray, and green paints straight from the tube, and began to prefer my own mixtures. Unlike blends that I created from mixtures of often primary colors, some of these tube paints began to appear dull, flat, uninteresting, and lifeless to me. Other tube paints looked stark, strident, unnatural and out of place in certain pictures. What a revelation! I began to notice details that I had not been aware of before. And I was starting to feel unhappy with a few of the colors on my palette.
Why did some paints, like some of the reds, greens, and browns, look so flat and dull? Everyone talks about ‘Transparent Watercolor,’ but what is it exactly? Are all watercolors transparent? And why is transparency important? How are opaque colors different from transparent colors? Where does the elusive ‘glow’ or luminescence of watercolor come from? Is it in certain pigments, or does it result from how the paint is applied? I decided to try to make my paintings glow!
As I studied and experimented, I learned more about the characteristics of pigments and how they behave. The issues were confusing! Some paints worked well in certain situations but not in others. Some colors mixed cleanly with others, but similar-appearing colors, when mixed with another color, turned into mud! Ugh! I realized that all watercolor pigments are NOT transparent or equal in intensity. All blues are not interchangeable. In fact, sometimes tubes of paint with the same name do not even contain the same pigments! How could one expect them to behave the same? And, further, some tube paints are not made from a single pigment but are mixtures of a number of pigments, each of which has its own characteristics.
HOW NOT TO MAKE ‘MUD’!
Jeanne Dobie, in Making Color Sing, describes how she makes vibrant, glowing color. She recommends transparent and pure color pigments as a base for your palette colors. To capture the ‘effect of light’ in watercolor, use transparent and single ingredient pigments! Jeanne says, “Because transparent colors permit the greatest amount of light to pass through to the paper, reflecting back to the viewer, they impart luminosity. Moreover, they remain transparent when mixed together – so there’s no mud!.. If you begin a watercolor with opaque pigments, you’ll lose the effect of light. Opaque pigments are denser and heavier, which greatly reduces the amount of light transmitted through to the paper. Because of this ‘thickness,’ an opaque pigment does not mix well with another opaque color. It only becomes thicker! If you mix two opaque pigments together, you are flirting with a muddy mixture. Should you mix three opaque pigments together, the result may be too lifeless to call a watercolor.”
Watercolor pigments are composed of several different types of materials. First, some pigments are made of ground MINERALS or EARTH. These have a tendency to float on the surface of the paper, whether transparent or not, and so may NOT be very good for mixing. (I think it is interesting that some mineral pigments are quite transparent — for example, genuine ultramarine blue, burnt sienna, raw sienna, cobalt blue, viridian, and manganese blue.) Second, some pigments are ORGANIC DYES. Third, other pigments are SYNTHETIC DYES. The dye pigments are NOT all transparent as one might expect, because some are combined with various fillers.
MY PALETTE COLOR CHANGES.
Gradually, I have added more transparent primary colors (red, yellow, blue) to my palette and reduced the number of opaque pigments. I have tried to find transparent colors made from a single pigment (i.e. ‘pure’, as Jeanne Dobie describes). I now have a wide variety of transparent red, yellow, and blue primaries which can be mixed into numerous clear variations. I chose each paint for a particular quality; while some are very similar, no two are exactly alike.
On my palette, I continue to keep some additional “occasional use” colors that are opaque, such as cerulean blue, cadmium red, Winsor Newton Payne’s gray, and burnt umber. Many greens I mix from primary colors, but I have a few transparent greens on my palette. I removed any ochres and use burnt umber with care, as they are opaque. I like the siennas because they are transparent or semi-transparent, depending on how diluted the mixed wash is. While the above earth colors look beautiful when wet, they do seem to lose their richness as they dry, appearing flat and somewhat dull. (I plan to discuss the specific colors that I have on my palette in a later blog. Stay tuned!)
Jeanne Dobie also maintains that selecting pure transparent pigments is just the start. An artist needs to learn about color relationships to use the colors successfully – color mixing could be the subject of yet another, later blog post, perhaps. And, yet, there is also a place for the opaque colors on your palette. “To complement the pretty (transparent) colors” and to enhance their jewel-like tones, you need to use more subtle, “non-brilliant mixtures.” Thus, my first discovery in the search for “GLOW” was that the glow begins with the use of transparent colors.
The second part of creating glow in a painting seems to be related to a technique called GLAZING. Most watercolor painters are aware that it is possible to paint one wash over another, a process called glazing. (The secret is to apply each wash, usually the lightest color first, to a THOROUGHLY DRY sheet of paper.) Now why would a painter want to do this? It seems like a lot of trouble! Is it worth it?
Yes, properly applied, layers of washes are what actually produce the characteristic GLOW of watercolor and a stained-glass effect that cannot be achieved by any other means. To achieve the much sought after GLOW FROM WITHIN in watercolor, an artist glazes layers of mostly transparent pigments. Pigments applied in glazes have MORE luminosity than the same colors mixed on the palette and applied in a single wash!
Once you have practiced your wash techniques and feel you are a bit proficient at them, here is the procedure for glazing: 1. Develop your glazes from transparent watercolors (eg. Indian yellow or Hansa yellow light, Winsor blue or Phthalo blue, Winsor red or pyrrol red). 2. Begin with your lightest pigment, usually a yellow. 3. Keep your washes DILUTED and transparent. 4. Make sure, VERY SURE, that all previous washes are COMPLETELY dry before a new wash or glaze is applied. 5. Use the most opaque paints toward the final stages of your painting. Using them in the initial stages runs the risk of creating mud or chalky washes. (I must give credit here to Don Rankin, who, in his book Mastering Glazing Techniques In Watercolor, gives these clear and simple ground rules for glazing.)
