Color imaging and computer graphics share many of the same problems. Color reproduction systems increasingly lean toward spectral image capture and reproduction, in an attempt to create images that match the originals under any given viewing condition. We set out to use a synthetic image generation technique to create images with full spectral radiometric data at each pixel, for use in color imaging systems analysis. While working on this task, we realized that the standard RGB color model used in computer graphics suffered from the same problems as the typical imaging system. These problems manifest as color errors, which are very noticeable when rendering or imaging metameric objects. Eliminating these errors requires using a more accuiewing condiepresentation. We review some of these alternative methods and strongly encourage their use when accurate color image synthesis is desired.
