Abstract
The maximum luminance of an object color is physically restricted by its illuminant condition. To understand whether human color vision behaves appropriately for this physical limitation when judging color appearance mode, we showed the relationship between the luminosity threshold for surface color mode perceptions and the luminance-chromaticity distribution of surrounding colors in a psychophysical experiment, then compared its result with the calculated physical limitation of object colors under given illuminant conditions. The results showed significant correlation between them, suggesting that human color vision has acquired a mechanism appropriate for the physical limitation of objects colors.
