Scaling and Thresholds of Color and Light Described by an Opponent Model of Color Vision Based on Psychophysical Data

A newly developed model for vision of color and light, based on psychophysical results and some physiological experiments with monkeys, defines equations to describe scaling and threshold data over a large range of luminances and chromaticities The luminance of central and surround fields vary between 1 and 10,000 cd/m2.
