Claim Text:
1. A chromic luminescent composition, said chromic luminescent composition having a first brightness and comprising: one or more non-luminescent materials having an absorption property with an absorption spectrum that at least partially overlaps with a spectrum of incident electromagnetic radiation from a light source, the one or more non-luminescent materials mixed with one or more luminescent materials to form a uniform dispersion, the one or more luminescent materials having an absorptive property and an emissive property that converts at least a portion of energy of the incident electromagnetic radiation from the light source to a lower energy wavelength, said one or more non-luminescent materials and said one or more luminescent materials being selected such that, upon exposure to the incident electromagnetic radiation from the light source, the luminescent material of the uniform dispersion creating an emission spectrum that substantially overlaps with a reflection spectrum from the non-luminescent material of the uniform dispersion whereupon the additive combination alters the brightness of the chromic luminescent composition to a second brightness.
