Patent ID: 7939239

Claim:
In combination, a light source and a subject, wherein the light source has an illumination spectrum characterized by a distinctively stronger emission peak at a predetermined wavelength within a visible spectrum compared to other wavelengths; and, the subject has a pigment applied thereto, wherein the pigment has a reflection spectrum characterized by one of a distinctively stronger reflection peak at the predetermined wavelength compared to said other wavelengths and a distinctively weaker reflection gap at the predetermined wavelength compared to said other wavelengths; wherein the pigment gives the subject a distinct appearance when illuminated by the light source, due to the emission peak matching one of the reflection peak and the reflection gap, as compared to a nominal appearance when illuminated by an alternate light source which does not include the distinctively stronger emission peak at the predetermined wavelength as compare to said other wavelengths; and wherein the emission peak corresponds to a primary color, and the illumination spectrum is further characterized by at least one additional distinct emission peak, such that the illumination spectrum provides simulated broadband illumination.
