The appearance of a color is significantly influenced by the illumination under which it is viewed. Perhaps the most important factors are the intensity and the spectral power distribution, or SPD, of the illumination source. The basic properties which may be used to define a viewing condition are the chromaticity and intensity of the illumination source, the reflectance of the background, and, the relative UV content of the source. viewing condition defined for the International Color Consortium (ICC) perceptual PCS should be considered as part of the specification of a reference interchange encoding, not a requirement to actually use D50 in the color management workflow. The v4 specification introduced a distinction between the PCS used for colorimetric and perceptual rendering intents. The viewing condition under which a color stimulus is viewed strongly influences its appearance.
