Abstract
On color constancy, the ability to perceive stable object color, it was shown that brighter surrounding colors had greater influence than dim colors. However, bright colors in real scenes, such as luminous objects and metallic luster, do not necessarily have information about its scene illumination. The question here is whether bright colors in the illuminant mode affect color constancy. The results showed that the effect of brightest surrounding colors on the color perception of a test surface diminished at the luminance balance where the brightest color appeared as an illuminant. This suggests that the visual system might accomplish color constancy using only surfaces in the surrounding colors.
