(a) Positions of the 25 stimuli in the MacLeod-Boynton chromaticity space used for the MDS experiment. (b) Raw group average MDS results. Best-fitting ellipses are shown through the set of eight data points corresponding to each of the three different saturations included in the set of stimuli. (c) Results of the Procrustes analysis. Group average MDS solutions were rotated to best coincide with the MacLeod-Boynton chromaticity diagram shown in (a).
