- The spectral reflectance curves for 132 samples of yarns, fabrics, and paints were kindly supplied by Rolf Kuehni of Verona Division, Baychem Corporation, representing Bayer AG, Leverkusen, Germany. Included were sample set MV68(Bayer AG) and set AA17 (Committee AA17 of the Fachnormenausschuss Farbe, Germany). The samples total 317 pairs which match in daylight, and 51 colors. The sets have been described by A. Brockes, Proceedings of the International Color Association (AIC) Color 69, Stockholm, 1969, p. 752.

- Wright points out in Reference 3, p. 143, that a general concept of metamerism, independent, as is the modulus of metamerism suggested here, of the illuminant and the observer, is valid; he suggests that the amplitudes of the loops serve as a modulus of metamerism, although at that time it was not recognized that the location of the loops (near 400, 480, 580, 660 nm) is characteristic of the normal human observer.

- Alternate wavelengths, combined in a test illuminant, are less useful. As is apparent from Fig. 6, the metamerism will show up often as a harder-to-see difference in brightness of the reflected lights, rather than as a difference in color, because the alternate wavelengths tend to be complementary and add to white.
