This reprinted update of the 1967 edition reflects color science developments in color matching, increment-threshold work, chromatic adaptation, and theoretical modeling of color discrimination and other color-vision phenomenon. The authors focus more on quantitative tools and basic principles than on qualitative material or highly theoretical color-vision modeling issues. Chapters cover physical data, the eye, colorimetry, photometry, visual equivalence and matching, uniform color scales, visual thresholds, and color-vision theories and models. Includes 41 pages of references, and appended tables and illustrations (none in color!). The authors' affiliations are unspecified. Annotation c. Book News, Inc., Portland, OR (booknews.com)
