dc.description.abstract A method, proposed by Umberger, for the identification of additive stimuli representative of the red, green, and blue primaries controlled by dyes obeying Beer's law was examined. The primary stability study suggests that for a set of colors created of various dye concentrations, the pattern of Umberger's primary distribution is a translation of the original colors on a chromaticity diagram. Results of a theoretical color reproduction study where the colormatching functions of Umberger's primaries were assumed as the color reproduction system's spectral sensitivities indicate an increase in metric chroma of reproduced colors. Color reproduction errors for a large number of colors were minimized for spectral sensitivities corresponding to Umberger's primaries controlled by dye concentrations resulting in an 18% transmittance gray color. A technique was proposed for optimizing the system's spectral sensitivities to colors constituting the reproduced scene. en_US
