Abstract

All colors which evoke the same hue and brightness are represented by a curve in the chromaticity diagram and have lower luminances for high saturations than for low. The various loci tend to converge on a point which represents an acceptable white under the conditions of adaptation produced by the surrounding color. The influence on adaptation of surrounding color beyond a ten-degree test field is of the same order of magnitude as the influence of the color of the comparison half of the test field.
