Rendering a color palette by light-emitting diodes

We present a new approach to the optimization of sources of white light based on colored light-emitting diodes (LEDs) and show that a pentachromatic source composed of LEDs with the equidistant peak wavelengths at about 450, 500, 550, 600, and 650nm renders all 1269 colors of the Munsell palette almost indistinguishably from daylight.
