Perceived white reflects a response norm that varies with adaptation, and individual differences in perceived white shrink when observers share a common white adapting stimulus — the white point is calibrated by the visual environment.

- XREF: connects to: White is the most inferior of colors of morals of superiority. It follows that whiteness is the lack of characteristics that make a theme and give it its facets of colors. ; White has special status among colors, experienced as achromatic or an absence of hue, and its perception is not explained by a simple null point of cone-opponent mechanisms but involves calibration to the visual environment. — What is white?; To what extent does environmental visual adaptation (e.g., living in extreme high- or low-chroma landscapes) shift an individual’s implicit cognitive associations between achromatic light and moral valence?
