This volume elucidates Jozef B. Cohen's matrix-R formulation of the algebra of color matching and color mixing. Cohen's method of colorimetric calculation, for which he received the Macbeth Award from the Inter-Society Color Council in 1992, continues to exert a pervasive impact on the color-science community. Visual Color and Color Mixture develops Cohen's signal achievement from its historical sources. It provides a thorough explanation of the implications of metamerism that will be of considerable use to researchers in industries concerned with the use of colorants, as well as to colorimetrists and color scientists.
