Summary

Optimizing indoor light source spectral power distributions for best color quality, this chapter describes a mathematical method to optimize a light source so as to obtain best color harmony for a set of test color combinations illuminated by this optimized light source. The chapter also describes a comprehensive method of the visual assessment of color quality. When talking about the color quality of indoor light sources, the interobserver variability of color perception and color cognition among the observers (or light source users) cannot be ignored. The chapter enumerates those mechanisms of color perception that may contribute to the interobserver variability of perceived color quality or color quality judgments, within the group of observers of normal color vision, while the challenges of improving the color quality for deficient color vision are not dealt with.
