One of the most enjoyable exercises we do in my Basic Dyeing class is making a simple colour wheel of fat 1/8s in plastic bags. I decided to do some more of this at home, using different primaries, and fat 1/4s. Above is the #1 wheel using Tangerine, Basic Red and Turquoise.
#2 wheel used Golden yellow, Cobalt Blue and Magenta.
#3 wheel was Lemon Yellow, Turkey Red and Medium Blue.
