The best explanation I've found is in the online book "The Dimensions of Colour" by David Briggs. In particular the section on "Colour Mixing in Paints" (http://www.huevaluechroma.com/061.php). You might have to read some of the preceding sections to get a complete understanding. The website https://www.handprint.com/ is also very good. In practice it is possible to mix a grey from coloured paints, but you need disproportionately much blue. Brown is just dark orange, and blue is the complementary colour to orange, so you need to move in the blue direction if you want to get to grey. Also, if you're using red, yellow and blue, you generally need less yellow than red. Try a ratio of 1:2:4 = R:Y:B. |
