You're probably familiar with the typical elementary school perspective on primary colors: fire engine red, blueberry flavor blue, and lemon yellow. These colors are fine, but in advanced color theory they're incredibly limiting.
In another post I'll talk abut hot-cool color theory and about the true six primary colors.
Today, however, I'm going to talk about making a variation on the primary colors. In the image above we have a "Primary Ochre Palette" -- Red Ochre, Yellow Ochre, and Vivianite. Using these you can create a complex series of colors together, excellent for landscapes, portraits, and still lifes.
