Abstract

This investigation is concerned with the amount of agreement among perceptual color scales constructed from liminal differences, large psychological intervals, and absolute judgment data. These comparisons were made for the same observers and for constant viewing conditions. Scales were constructed for mixtures of yellow and blue primaries produced by filtered light, at constant luminance. Each of five observers completed three experiments from which color scales were derived: successive bisection, yielding an equal-interval scale; color matching, yielding an integrated just-noticeable difference scale; and absolute judgment, yielding an equal-discriminability scale. Very good agreement was found between the just-noticeable difference and equal-discriminability scales for all observers. The correspondence between the bisection scales and the other scales ranged from very good to very poor for different observers.
