Several years ago made this color wheel based on the Munsell system. It’s oil paint on an 11 x 14 canvas board. I cut the wheel dial from some thick cardboard that backed a drawing pad. It’s got the main windows and discord windows. I wrote in the paint colors where they fell on the wheel.
Everyone has their favored color system. I like this one pretty well. 
I need to make a mini one on a 5×7 canvas board.
