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 650 nm renders all 1269 colors of the Munsell palette almost indistinguishably from daylight.
