12 Hue Color Wheel

I needed some dyed yarn - 'primaries & secondaries' for an upcoming workshop.

I had originally planned to match the colors in the Munsell 10 hue wheel but in the end decided to go with the more common 12 hue color wheel.

I attempted to match the colors in the hue wheel in the Art of Color by Itten with those in my 10% graduation exercise.

Matching the colors reminded me of an argument I had with my chemistry teacher in high school. We mixed some chemicals and were to write down what color the liquid turned. The teacher and I argued as to whether it was yellow or green. I found it odd we could not agree as to what we saw.

Color is perplexing in so many ways.
