Abstract
We prototyped a lighting system for color enhancement with maintaining a white appearance using low-cost multicolor LEDs. We bought LEDs of several colors in local electronic parts shops, and spectral power distributions of them were evaluated for synthesizing objective lights. Five LEDs were chosen for natural color observation of the object, and three of them were used for color enhancement. Experiments were conducted using an assembled LED lighting, and a color chart and reddish and blueish color patches were enhanced with maintaining white appearance chromatically.
