The phenomenon of colour constancy in human visual perception keeps surface colours
constant, despite changes in their reflected light due to changing illumination. Although …

Typical daylight extends from blue (morning sky) to orangey red (evening sky) and is
represented mathematically as the Daylight Locus in color space. In this study, we …

The chromaticities of natural daylights cluster around the blackbody locus. We investigated
whether the mechanisms that mediate human color constancy embody this statistical …

In everyday experience, perceived colors of objects remain approximately constant under
changes in illumination. This constancy is helpful for identifying objects across viewing …

We measured discrimination thresholds for illumination changes along different chromatic
directions starting from chromatically biased reference illuminations. Participants viewed a …

The perception of color poses daunting challenges, because the light spectrum reaching the
eye depends on both the reflectance of objects and the spectrum of the illuminating light …

Color constancy is the ability to assign a constant color to an object independent of changes
in illumination. Color constancy is achieved by taking context information into account …

For a visual system to possess color constancy across varying illumination, chromatic
signals from a scene must remain constant at some neural stage. We found that …

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 …

Color constancy is a prime example of a perceptual constancy, giving stability to mental
representations of objects in an unstable world. Yet color constancy is highly variable …
