Abstract

We shall be concerned in this study primarily with the relation between "illumination" and "colour". White paper is recognized as "white" whether seen in daylight or in moonlight; the same holds for the "black" of black velvet. The paper will also be "white" when seen in the greenish shadows of an arbour or under an ordinary electric light. With coloured objects (blue, red, etc.) analogous although less extensive observations may be made; a blue paper is seen as practically "blue" even under the reddish-yellow light of a gas lamp. These discrepancies between experience and physical light conditions give rise to the problem with which we are here concerned. If, for example, degree of whiteness were a simple function of the intensity of light reflected from the surface, then white paper in a reduced light should look blacker than intensely illuminated black velvet. The fact that this does not ordinarily occur has been designated by Hering as "the approximate constancy of the colour of visual objects", or, as we shall hereafter call it, "colour constancy." (The complete version of this article appeared as "Die 'Farbenkonstanz' der Sehdinge," Handbuch. der normalen und pathologischen Physiologie, 1929, 12, 594-678.) [Original editor note: With the exception of the last experiment (pp. 674 f.) this paper is itself a summary of a large number of books and articles.
