Improved color fundamentals offer a new view on photometric additivity
article
New action spectra are derived for the foveal cones on the basis of three assumptions: (1) the Stiles-Burch (1959) colorimetric data are better than CIE 1931; (2) the long wavelength flanks of the dichromatic luminosity functions offer better anchorage than the confusion loci; and (3) the relative mutual heights per receptor can be derived from the Bezold-Brucke effect. Since these assumptions do not include photometric data, we could at the end ask how L(λ), M(λ) and S(λ) combine to V(λ). The best answer appeared to be V(λ) = 0.68 L(λ)+ 0.34 M(λ) - 0.02 S(λ), reflecting both relative population densities and a negative input of the S-system to luminance.
