Abstract : Mellinger obtained a six-dimensional color space as the result of a multidimensional scaling experiment, rather than a three-dimensional model whick would have been expected in terms of classical color theory. In the present experiment, a comparison of different subjects indicated a very high degree of uniformity in the subjects' responses. The analysis yielded a twelve-dimensional multidimensional scale rather than the two(over) dimensional scale which would have been predicted by classical color theory. Upon transforming the interpoint distances by an exponential transformation and carrying out a reanalysis using the transformed distances, a two-dimensional multidimensional scale resulted. The configuration of stimuli within this two-dimensional multidimensional scale conformed very closely to the predictions of classical color theory. Mellinger's data were then obtained and reanalyzed after being appropriately transformed. The result obtained here was also much more nearly in conformity with the predictions of classical color theory. (Author)
