## Abstract West and Brill (J Math Biol 1982;15:249–258) posed necessary and sufficient conditions on reflectance for Von Kries ratios to be illuminant‐invariant. The statement of the conditions allowed the illuminant unlimited freedom in a function subspace. If the illuminant change is only a pair

Exploring conditions under which von Kries ratios are illuminant-invariant, C. van Trigt produces an error expression, whose first term he claims must be small, as when the visual sensitivities approximate delta functions in wavelength. However, by restricting illuminant and reflectance spectra in s
