Abstract
Three observers each judged differences between pairs of 25 colors in each of 12 intersecting oblique planes in the color space of the uniform color scales of the Optical Society of America (OSA). For each set of 25 colors, a three-dimensional configuration of points was determined for each observer, by use of the KYST algorithm. Equal judgments of differences between pairs of the colors are, as nearly as possible, represented in the configurations by equal distances between the points that represent the colors, and greater judgments by greater distances. The rms relative standard deviations of the judgments ranged from 0.061 to 0.214. The stress, as determined by the KYST algorithm, ranged from 0.048 to 0.151. In the configurations, the surfaces that correspond to the oblique planes in OSA color space are curved significantly.
