Let’s discuss the primary colors as they relate to art, or more specifically, painting. These are the first colors you’ll learn about in art. Even my 1-year-old daughter, Elora, has been introduced to the primary colors through her children’s shows and at daycare. Perhaps it’s because we’re introduced to the primary colors so early in life that many of us take them for granted. But make no mistake, the primary colors are at the heart of color theory and mixing. It’s essential that you truly understand what they mean and how to use them effectively if you want to paint well.

What Are the Primary Colors
The primary colors are red, yellow, and blue. These colors are, in theory, able to mix all the other colors in the visible spectrum. They also cannot be created by mixing other colors. You’ll find them evenly spaced around the color wheel, forming a triangular relationship.
In practice, however, color is not so simple. There are many different reds, yellows, and blues available to us. Cadmium red, alizarin red, spectrum red, crimson red, etc. Each color has a different position on the color wheel. Which of these colors are the true primary colors? The answer would be the paints which represent the purest and most saturated forms of red, yellow, and blue. Cadmium red, cadmium yellow, and cobalt blue would be good picks. These are what I use as the primary colors on my palette. They are vivid and relatively pure compared to other paints. But it’s worth noting they are not perfect primary colors in that they do not hold up to the definition of being able to mix all the other colors in the visible spectrum. You would struggle to mix a good purple or a good green with these colors.
A better representation of true primary colors would be yellow (say cadmium yellow light), cyan, and magenta. With these colors, you would be able to mix a far wider gamut of colors. The Handprint website has some detailed information on this if you want to go deeper.
The reasons I still adopt red, yellow, and blue as the primary colors, despite their obvious limitations for that role, are for simplicity and to be consistent with other art education.
It’s important to remember that color theory is not a perfect science in art. There are far too many variables for it to be treated like that. Our paints vary in terms of brand, batch, age, condition, etc. Just look at the difference between cadmium yellow by Winsor and Newton and cadmium yellow by Art Spectrum:
The most important aspect of color is how you use it in your work. It doesn’t matter how you got there. Sometimes, that means simplifying the theory into a more practical form. That’s what color theory is in art. It’s not always scientifically correct, but it does the trick.
Primary Color Mixing
When you mix two primary colors together, you get a secondary color. Red and yellow = orange. Yellow and blue = green. Red and blue = purple. Here you can see the shortcomings of cadmium red, cadmium yellow, and cobalt blue as primary colors. They do well with orange, but not so much with green and purple. The best I could do for purple was a dull, cool red.
When you mix all three primary colors together, you get some variation of gray or mud.
When you add black to a primary color, it gets darker in value. It also gets weaker in saturation.
When you add gray to a primary color, it gets weaker in saturation. It will also get lighter or darker in the direction of the gray.
When you mix a primary color with its complementary color, you make the color weaker in saturation. It will also get lighter or darker in the direction of the complementary. In the right proportions, mixing two complementary colors should create gray.
Warm and Cool Primary Colors
In painting, there are warm and cool variations of the primary colors. These definitions rely on the positioning of the color on the color wheel. A primary color that leans towards a warm color is considered warm and one that leans towards a cool color is considered cool. And keep in mind, I am using the term “primary color” loosely. Below are some examples:
Manganese blue – cool (leans towards yellow on the color wheel)
Ultramarine blue – warm (leans towards red on the color wheel)
Cadmium yellow deep – warm (leans towards red on the color wheel)
Cadmium lemon – cool (leans towards blue on the color wheel)
Cadmium scarlet – warm (leans towards yellow on the color wheel)
Alizarin crimson – cool (leans towards blue on the color wheel)
This is important knowledge for mixing vivid secondary colors (orange, green, and purple). To mix vivid secondary colors, you must combine primary colors that lean towards each other on the color wheel and do not contain traces of a third primary. Remember, when you mix all three primary colors together, you get mud.
In the image below, the two blues from top to bottom are cobalt blue and manganese blue. The yellows from left to right are cadmium yellow in Winsor and Newton, cadmium yellow in Art Spectrum, and cadmium yellow light. I reference the brands of the first two yellow paints as they appear to differ considerably in temperature; the Winsor and Newton yellow is much warmer. Notice how the cobalt blue produces dull greens. The most vivid pairing was manganese blue with cadmium yellow light, though the image did a poor job at capturing this. Cadmium yellow in Art Spectrum with manganese blue was a close second. (I did this experiment previously using more blues and yellows. You can read about that here.)

Fechin on the Primary Colors
Nicolai Fechin, a true artist’s artist, had some wise words on the primary colors:
“As a matter of fact an artist has to deal with only three basic colors: red, blue, yellow (all the rest are combinations of these fundamental colors). Everyone knows this, but few pay attention to the fact. Thus the first step for the artist to learn to see these primary colors and to distinguish them separately one from the other.” (Source)
“To avoid murky results, it is necessary to learn how to use the three basic colors and to apply them, layer upon layer, in such a way that the underlying color shows through the next application. For instance, one can use blue paint, apply over it some red in such a manner that the blue and the red are seen simultaneously and thus produce the impression of a violet vibration. If, in the same careful manner, one puts upon his first combination a yellow color, a complete harmonization is reached – the colors are not mixed, but built one upon the other, retaining the full intensity of their vibrations.” (Source)
Primary Colors of Light
The primary colors of light are different from that of our paints. They are red, blue, and green. This is a complex area and requires a separate post. I’ll let you know once it is published.
