Prediction of color appearance under various adapting conditions

Abstract

Abstract A model of color vision is given to predict color appearance of object colors under various illuminants and illuminance levels. The model constitutes a uniform color‐appearance space under any adapting condition, and can predict the metric quantities relating to the following color perceptions: (1) constant‐hue loci, (2) the Munsell color scheme, (3) the increase of brightness contrast of nonselective samples with increasing adapting‐illuminance level, (4) the Helson‐Judd effect, and (5) the increase of colorfulness of chromatic samples with increasing adapting‐illuminance level.
