It has been suggested that ratios of photoreceptor catches for the light reflected by pairs of surfaces play an important role in color vision (Foster & Nascimento, 1994). We provide results from simulations showing that L, M and S ratios obtained from surface pairs consisting of a colored surface and an achromatic surface of the same luminosity reach their extreme values for a few specific colored surfaces, namely red, green, blue and yellow surfaces. There is a striking correspondence between the colors singled out in this way and the ones singled out in cross-cultural studies of color naming (Regier, Kay & Cook, 2005). These results will be compared with a related approach proposed in Philipona & O'Regan (in press), which further addressed the question of unique hues and hue cancellation.
