How to darken a color
How to dull a color
How to mix grays
This exercise is designed to show how to darken a color and dull a color and how to mix interesting neutrals (grays).
Use three sets of complementary colors:
*how to mix the best (brightest) oange, green, and purple is on the previous blog post.
Make a grid like the one in the photo.
Start with complementary colors at top and bottom, then gradually add increasing amounts of the complementary color, When you reach the middle the result will be unidentifiable as either complement. The result will be a neutral (gray) color that will often need to use in your paintings.
Notice there are two columns for each set of complements. The second column is a "tinted" version of the first column achieved by adding white to the colors mixed in the first column.
The first time you add a little of the complement is get darker and duller and this continues until you reach the middle (the fourth from the top grid where the color looks "muddy", dull and gray.
Don't worry about making this perfect. What counts is getting the concept of how to make a color darker by using its complement and seeing how you can predict what happens to color.
