Over the years I’ve tried many different ways to mix the colors in the middle of a three primary triangle. Nothing seemed to work until I came up with what I call “Base Mixing.”
Base Mixing is a two part process that starts with mixing a series of purple colors along the bottom of the triangle, running from a primary “blue/cyan” to a primary “red/magenta.” The second step is then to mix scales with each of the base colors to a primary lemon or zinc yellow.
I have found that no matter what medium I use – polymer, paint, crayons, pencils or dye – the resulting color scales always follow the same color flow.
For example, when you start with a Blue Violet base color (think of that beautiful, rich color that some people call blue and some call purple) you will always run through a gray, a gray green and an olive green on your way to yellow.
The gray will show up at different levels of the triangle depending on the tinting strength of your Yellow in comparison with the Blue Violet but some version of gray will fall along this line.
Exploring the way color flows from the various purple base colors to yellow will help you learn how to mix and shift colors without using formulas.
Try it in polymer or in any medium that you use!
