Color Chart (in progress)

Here is the chart I'm doing for my class instructed by Jane Jones at the Denver Art Students League. It includes warm and cool versions of each primary and secondary color as well as some earth tones, white and black. It's not quite finished - I still need to add my earth tones. This chart has two inch squares that I've been mixing with a palette knife. Some of the colors are so dark that they only reveal themselves if you add white. I've discovered that some of my colors create mixes that I never would have imagined! It's tedious but fascinating. I will continue working on this chart until its done and then we will be working on value scales, intensity charts, etc. It's a slow process but I'm learning things that I would never know if I didn't just slow down and do this!
