The story of the Color Wheel is a very interesting one which I would strongly suggest reading over at Imprint, for a full history class. But in the meantime here are visuals that are most appealing to me. All of these antique color wheels and color cards were hand made in the 16th, 17th and 18th Century! I would love one of these!
