This one is the each color on the color wheel and then tints (adding white), tones (adding gray) and shades (adding black) to each color...showing their progression. There were percentages and so forth, but that gets into the boring side.

This one shows how mixing complementary colors make neutrals. This shows Blue blending into Red Orange, Orange, and Yellow Orange, then it shows red blending into yellow green, green, and blue green, and last it shows yellow blending into red violet, violet and then blue violet. I don't want to bore you with the percentages...It was informative but I am glad they are done.
