Abstract
The accurate display of synthetic images requires careful attention to color. Simply modeling color with an RGB triplet leads to color aliasing. Most color antialiasing techniques begin with a specification of color as a spectral energy distribution. There are two apparent hurdles to be overcome to support the spectral model in rendering systems. One is the difficulty of interactively designing a spectral description of a desired color. The other problem is the difficulty of converting existing and useful libraries of RGB triplets into equivalent spectral representations. A simple method that takes as input an RGB triplet viewed on a given monitor and computes a corresponding spectrum for use in a rendering system is presented.Keywords
