Abstract
In this paper a new color conversion method to replace the RGB approximation based on the perceived change in color when a colored light source illuminates a surface is proposed. In our study 1200 uniformly distributed samples were taken from Commission Internationale de l’Eclairage 1976 L*a*b* uniform color space and used to construct a uniform subset. Photographic patches of the colors in this subset were then subjected to color light sources and the color changes were measured. From these measurements rules which govern the corresponding change within the color space were determined. Changes within the color space were then defined by simple linear equations for any light source illuminating any surface. Lastly, experiments were conducted to confirm that color conversion within the CIE color space generates more realistic images than RGB approximations for a variety of light sources.
