Blue and Yellow Dont Make Green: Or How to Mix the Color You Want-Every Time by Michael WilcoxThe ideas in this book are probably not news to artists, but they were new to me, so it was instructive. But, even though its a short book, he explains things to death. There was *lots* of repetition of the same basic idea.
The basic idea is that when you mix blue and yellow, they dont always make a nice, clear green as you might expect based on what you were taught in school. You might end up with a muddy brownish olive instead.
The reason that might happen is because no paint color is true blue, yellow, or red. All yellows are either greenish or reddish; all reds will be either bluish or yellowish; and all blues will have either a yellowish or reddish cast to them. If you mix blue with a reddish yellow, its almost the same as if you mixed in a little red along with the blue and yellow, so you come out with a muddy greenish color. To get a nice, clear green you have to mix the blue with a bluish yellow. And the same for the other colors. A yellowish red mixed with a reddish yellow will give a clear orange; if you use a bluish red or a bluish yellow, or both, the color will be more subdued and brownish. According to the author, you mostly only need six colors -- two versions of each primary color -- to mix just about any color you want to use, so you can save a lot of money by not buying colors you dont need. Once you read this basic idea it seems obvious, like something you probably should have been able to figure out.
Thats not the only idea in the book; the author does tell a little bit about what color names or ingredients tip you off as to whether youve got a bluish or a yellowish red, for example, in case youre not good at figuring it out. And he talks about which pigments tend to be higher quality, which tend to be more opaque and which transparent, and which colors other than the primaries might be useful and why. Still, some of the Amazon reviews Ive read cite books on the same topic that are supposed to be better, those might be worth checking out. I might take a look at Color Choices by Stephen Quiller and Color Right from the Start by Hilary Page.
There are two types of color mixing : additive and subtractive. In both cases, mixing is typically described in terms of three colors and three secondary colors colors made by mixing two of the three primary colors in equal amounts. The additive mixing of colors is not commonly taught to children, as it does not correspond to the mixing of physical substances such as paint which would correspond to subtractive mixing. Two beams of light that are superimposed mix their colors additively. By convention, the three primary colors in additive mixing are red , green , and blue. In the absence of light of any color, the result is black. If all three primary colors of light are mixed in equal proportions, the result is neutral gray or white.

By adding the three primaries of a computer screen in various proportions all hues should be obtainable. The primaries are red R , green G and blue B. It is obvious that R and B can give bluered hues, such as violet, magenta, purple. It is also obvious that G and B can give turquoise, which is a bluegreen hue. But how can R and G give yellow? It is not as mysterious as it might seem.
