Whether you are a painter, dyer or polymer artist, I believe polymer clay is the best material for beginning color exercises because it is measurable, easy to use, not messy, not expensive and lets you mix colors right in your hand.
There are now many brands to choose from. I am most familiar with Premo brand though I have done the exercises in all the clays. For the first round of color studies starting in January, you will need one two ounce block of white and one two ounce block in each of the colors listed for your preferred brand of clay.
