ABSTRACT:
A light source for categorical color perception has major light emitting bands in ranges from 530 to 580 and from 600 to 650, with correlated color temperature of the lamp light color in a range from 1700 to 6500 and with DUV (distance from perfect radiator locus on UV coordinates) in a range from 0 to 70, and allows categorical perception of at least red, green, blue, yellow and white of surface colors of an illuminated object.
