Wavelength peaks of human cone spectral sensitivities and of opponent chromatic responses from hue cancellation experiments.

These data represent, or are calculated from, experimental data. Under References only first authors are listed. Wyszecki (55), (56), and (57), refer respectively to Wyszecki & Stiles (1967) Konig-type fundamentals, Vos & Walraven (1978) fundamentals, and Stiles (1953, 1959) field sensitivities for π1, π4, and π5 mechanisms. In Fuld (1991), and in Kulp & Fuld (1995), data are given at large (20 nm) intervals so mean data for the 3 or 4 subjects respectively were plotted, curves drawn and peaks interpolated to nearest 5 nm as listed above. Takahashi (30) gives several troland levels for 8700 K color temperature and 2 subjects:#denotes 50 td,†is 500 td, and*is 5000 td.Two troland levels are shown for 5200 K and 1 subject:#Ldenotes 50 td,†Lis 500 td.
