Color is a fascinating subject, touching on physics, physiology, psychology, art, and philosopy. Here I am keeping some notes and references on color.

“Unique colors” based on the opponent-process model of human color vision from an article by Kuehni. The colors shown are approximations in the sRGB color space to the Munsell values 5R5/14, 5G6/8, 5Y8/10, 5PB5/12, N9, and N1. The background is N5. Approximate sRGB values are from Werth's Virtual Munsell Color Wheel.

Here are some interesting sites and articles:

Some random human skin colors. These cover the range of Munsell colors: Hue: 2.5-7.5 YR, Value: 2-7, Chroma 2-4. A high-chroma shade of YR is called “orange” in modern English. Appearance will vary with your monitor's color balance.
