This section will explain the color constancy theory and the white balance method, before discussing the color constancy method based on content awareness.
However, the human visual system still recognizes the object because of color constancy. For example, the borders of traffic signs in road images are perceived as red regardless of whether it is daytime or nighttime.

After all, it will exhibit color constancy when it is viewed there as well.
(35) How, exactly, to characterize color constancy is itself a contested topic.

Prior investigations have failed to clarify whether color constancy is an innate capability of the retina's cone cells or it's acquired only with help from the brain's visual system.

Metamerism may pose the problem, but color constancy provides the solution.
A sampling of topics includes relations between color stimuli, light sources, metamerism and color constancy, RGB colorimetry, colorant mixtures, and models of color appearance for stimuli of different sizes.
Through an examination of the phenomena of approximate color constancy, metamerism, and simultaneous contrast, as well as the mechanisms that underlie them, the present paper argues that although Tye's candidate for surface color, spectral reflectance, satisfies (P2), it does not satisfy (P1).--Correspondence to: chardin1@twcny.rr.com
