ception. Our retinas have (basically) three

types of color photoreceptor cone cells which

respond to wavelengths of visible light with

different spectral response curves.

Multispec-

tral color systems for future imaging systems

are under development that would eventually

allow for presentation of a greater range of

components (red, green, and blue) are gener-
