helpful that came from "Gene" . . . does anyone know if this was a post, or
something I copied long ago from a web site (before I knew I'd be sharing
it with others)??
If you add two complements together -in equal proportion - you will get
some form of brown.
If you add yellow and violet, the result is the ochers. If you add red and
green, you get the umbers. And if it's orange and blue, the product is the
If you add them together in "unequal" proportion - 75/25 for instance, the
result will still be close to a brown, but it will be more characteristic

auburn, walnut, seal, and many other colors are the result of mixing two
complements together in equal or unequal proportion.
You are able to obtain these results because complement pairs contain all
