  ABSTRACT = {Psychophysical studies suggest that different colors have different
    perceptual status: red and blue for example are thought of as elementary
    sensations whereas yellowish green is not. The dominant account for
    such perceptual asymmetries attributes them to specificities of the
    neuronal representation of colors. Alternative accounts involve cultural
    or linguistic arguments. What these accounts have in common is the
    idea that there are no asymmetries in the physics of light and surfaces
    that could underlie the perceptual structure of colors, and this
    is why neuronal or cultural processes must be invoked as the essential
    underlying mechanisms that structure color perception. Here, we suggest
    a biological approach for surface reflection properties that takes
    into account only the information about light that is accessible
    to an organism given the photopigments it possesses, and we show
    that now asymmetries appear in the behavior of surfaces with respect
    to light. These asymmetries provide a classification of surface properties
    that turns out to be identical to the one observed in linguistic
    color categorization across numerous cultures, as pinned down by
    cross cultural studies. Further, we show that data from psychophysical
    studies about unique hues and hue cancellation are consistent with
    the viewpoint that stimuli reported by observers as special are those
    associated with this singularity-based categorization of surfaces
    under a standard illuminant. The approach predicts that unique blue
    and unique yellow should be aligned in chromatic space while unique
    red and unique green should not, a fact usually conjectured to result
    from nonlinearities in chromatic pathways.},
