This document discusses color theory and early color models. It covers:
- Isaac Newton's discovery of the additive color system and the traditional color wheel model for subtractive colors.
- Early color theorists like Runge, Munsell, and Itten who developed color models to describe hue, value, saturation. Itten created a color star and wheel model.
- Itten identified 7 contrasts of color including value, saturation, and warm-cool, which are demonstrated in examples. Students are assigned to design a masque demonstrating intensity or warm-cool contrasts crossing a dividing line.
