Abstract: 

A central problem in color vision is how color discrimination varies over color space. MacAdam (1942) attacked the problem in an elegant set of experiments. He developed a special color mixer which produced a bipartite disc consisting of a fixed half field and a variable half field. Both halves were mixtures of lights derived from the same source and which passed through the same two color selective filters. The experimenter determined the relative amount of the two lights in the fixed half and the observer repeatedly adjusted the relative amount of the lights in the variable half. A large number of color filters sets were selected and trimmed by additional neutral filters so as to produce equally luminous primaries at many different points in the CIE diagram. By using a number of carefully chosen sets of these filters, fixed lights at the same point in the diagram could be obtained with several pairs of filters allowing the matching half of the field to be adjustable along different lines through that point.
