ABSTRACT:
A method of preparing a desired photoluminescent color pigment having a predictable color and spectral response under ambient illuminating radiation and in the dark, comprising the steps of: choosing at least one target color having a dominant wavelength and selected spectral response in the presence of ambient illuminating radiation and in the dark; and mixing by weight about 87-97.8% phosphorescent pigments, about 2-10% fluorescent pigments and about 0.2-3% common pigments, each having a dominant wavelength and spectral response near said target color, to produce said spectral response.
