title: Additivity of dichromatic color matches to short-wavelength lights.
abstract: The additivity of color matches to short-wavelength lights was examined in observers who behaved as red-green dichromats under the stimulus conditions used. Color matches were obtained at several luminance levels and on several different adapting backgrounds. The range of mixtures acceptable as a match and the midpoint of this range varied considerably over different conditions. However, for each observer, a set of mixtures that remained a match under all conditions could always be found. Results suggest that the additivity laws hold for these observers in the sense that there is a color match that remains a match under all conditions.
