Abstract
Color information is processed by the retina and lateral geniculate along principal dimensions known as the cardinal directions of color space. Individual differences impacting the direction of these cardinal axes exist within the normal population and are influenced by individual variation in lens density, macular pigment, photopigment opsins, photoreceptor optical density, and relative cone numbers. The same factors that influence color differences also impact luminance. We modeled and empirically tested how well tilts in the equiluminant plane are correlated with rotations in the cardinal axes. Our results show that �" especially in the SvsLM axis �" cardinal axis rotation can be partially predicted by luminance settings.
