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.
Yoichi Sugita of the Neuroscience Research Institute in Tsukuba, Japan, explored color constancy in four macaque monkeys that had been raised from age 1 month to 1 year in a room illuminated by light with a highly restricted range of wavelengths, which ensured that the animals couldn't discern a normal array of colors.
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).
With optimized color constancy, the swatches are individually packaged and are free of any backing paper or adhesives that affect the color appearance and spectral readings.
Outperforming the color constancy and brightness of previous LED designs, 6-lead MultiLEDs can be arranged closely together and flat on the board, resulting in light that is distributed more evenly.
