Individual differences in the color matches made by normal observers can be attributed in part to small interobserver variations in the spectral peaks (lambda max) of the cone sensitivities. I compared two different analyses of these lambda max variations that were both based on the Stiles-Burch 10 degrees color-matching functions [Opt. Acta 6, 1 (1959)]: one that suggested that the lambda max values for individual cone classes fall into discrete subgroups [J. Neitz and G. H. Jacobs, in Colour Vision Deficiencies IX, B. Drum and G. Verriest, eds. (Kluwer Academic, Dordrecht, The Netherlands, 1989)] and one that failed to find discrete clustering [J. Opt. Soc. Am. A 5, 1722 (1988)]. I conclude that there is not strong evidence for discrete lambda max variations in the Stiles-Burch matches.
