Abstract

We propose a method to enhance color saturation while keeping the color appearance of white by controlling the spectral power distribution (SPD) of illumination. A color chart is used to design the SPD of illumination, which enables us to enhance several colors at the same time. In experiments, a sixteen-color LED lighting system was used as a light source. The intensity of each colored light can be modulated and is determined using three color patches of the X-Rite ColorChecker. The color checker and multicolor wood-block prints were used to evaluate the results of color enhancement. The color distributions of these objects before and after changing the SPD of illumination were compared on a chromaticity diagram. Results show that the selected three colors are well enhanced while keeping metameric white and the color balance under daylight.
