Abstract

Partitive color mixing is the process by which the human eye integrates different neighboring colors to result in a single uniform surface. This process is convex: The perceived color is the weighted average of a small set of basis colors, and given that the weights represent the relative area of each color, they must sum to one. We present an efficient algorithm that generates a small number of new, natural bases such that a large set of spectra can be adequately expressed as a convex combination of these bases. Our results show that 9-11 bases are sufficient to represent a set of 1269 Munsell surfaces within the convex model.
