“…Illumination for enhancing the color of target objects are required in the medical field and food retail industry for enhancing an observer's impression or attracting an observer's attention, and several methods for optimizing the spectral power distribution (SPD) of illumination have been proposed [1][2][3][4]. Some of them have been implemented using a multicolor LED lighting system.…”

We used low-cost multicolor LEDs to prototype a lighting system for color enhancement with white appearance maintained. We bought LEDs of several colors at local electronic parts shops, and evaluated their spectral power distributions for synthesizing lights for illumination. Five LEDs were chosen for natural color observation of the object, and three of them were used for color enhancement. Experiments conducted using the assembled LED lighting system and a color chart showed that reddish and blueish color patches were enhanced with white appearance chromatically maintained.
