Claim:
1. A method of altering a first emission spectrum of visible light emitted from a light emitting source with a first luminosity, when energized, comprising: obtaining a first visible light emission spectrum emitted from a light emitting source including the intensity of wavelengths within the visible spectrum; determining a plurality of wavelengths of the first visible light emission spectrum with intensities less than that of a desired second visible light emission spectrum; selecting a plurality of differing substantially transparent pigments that are effective in increasing the intensity of the plurality of wavelengths when the first visible light emission spectrum is emitted through the transparent pigments; and applying the plurality of differing substantially transparent pigments to the light emitting source in a first density to alter the first emission spectrum of the light emitting source by increasing the intensity of the plurality of wavelengths.
