ABSTRACT:
An apparatus for "color mode switching," which enables duplication of daylight chromaticity for each color family. The present invention emits a selected spectral distribution of light which duplicates the effect of daylight, on a color-by-color basis. This effect is accomplished by a specific arrangement of specialized fluorescent and incandescent lamps which are switched (on/off) in a different pattern for each color family. The device has application anywhere color matching is required, including the after market for automobiles.
