To what extent do observers' judgments of surface color with natural scenes depend on
global image statistics? To address this question, a psychophysical experiment was …

Observers can generally make reliable judgments of surface color in natural scenes despite
changes in an illuminant that is out of view. This ability has sometimes been attributed to …

A quarter of a century ago, the first systematic behavioral experiments were performed to
clarify the nature of color constancy—the effect whereby the perceived color of a surface …

The human visual system has the ability to perceive approximately constant surface colors
despite changes in the retinal input that are induced by changes in illumination. Based on …

In natural complex environments, the elevation of the sun and the presence of occluding
objects and mutual reflections cause variations in the spectral composition of the local …

Color constancy—by which objects tend to appear the same color under changes in
illumination—is most likely achieved by several mechanisms, operating at different levels in …

Relational color constancy refers to the constancy of the perceived relations between the
colors of surfaces of a scene under changes in the spectral composition of the illuminant …

Spectral optimization for naturalness and preference was carried out empirically in a set of
psychophysical experiments in which observers adjusted the spectral composition of the …

The visual stimulus associated with an object surface varies with the illumination falling on
the object. Constancy of perceived surface colour under changing illumination implies that …

Color perception depends profoundly on adaptation processes that adjust sensitivity in
response to the prevailing pattern of stimulation. We examined how color sensitivity and …
