The appearance of colors produced by a minimum‐energy stimulus and two pairs of fundamental colors

摘要

AbstractThis article presents the results of experiments designed to measure the color appearance produced by a minimum‐energy stimulus within very small color fields and exposed for a very short duration. The experiments also revealed the common nature of colors in both spatial and temporal reductions. The hue is shifted toward either red or green and then toward a line connecting yellow and blue on the chromaticity diagram. The decrease and increase in saturation and brightness, respectively, correspond to this variation in hue. The nature of the results pertaining to the mechanism of color perception led to the assumption that a color‐sensation mechanism consisting of two pairs of fundamental colors acted functionally. These fundamental colors were calculated from the variations of the results obtained in color space, and were defined respectively as 513C, 510, 585, and 484
