Brown

Abstract

Purples and pinks and variations of these colors, which are not part of the spectrum, can be made by combining colors from the blue and the red end of the spectrum. All the other colors – blue, violet, indigo, green, yellow, orange, and red and the transitions between them -- ought to be represented, at some degree of saturation, by the spectrum itself. White, of course, is the combination of all spectal colors, and black is the complete absence of them. But if that’s the case, then where does one find brown on the spectrum? What color is brown? What colors must be combined to produce it?
