“…Women in particular appeared to be more successful in discriminating high and low quality stimuli. Our results are consistent with, and provide further evidence for, the idea that sexual selection through skin color discrimination may have contributed to the evolution of primate color vision in females (Waitt et al 2003;Changizi et al 2006). An enhanced ability to detect and respond to color cues in facial skin is likely to have fitness effects through more accurate discrimination of mate quality and health, potentially providing increased indirect and direct benefits to women.…”

Cues available in facial skin are used to assess mate quality in humans and non-human primates. In men, perception of skin healthiness and facial attractiveness are associated with heterozygosity at genes in the major histocompatibility complex, with potential implications for securing direct benefits through mate choice. There is, however, some debate as to the precise nature of the information available in skin that is used in health and attractiveness judgments. Here we investigate whether color cues are important in discrimination of skin healthiness and facial attractiveness in men's faces. We presented images of men judged to have attractive or unattractive faces, and healthy or less healthy skin, to independent raters in either full-color or gray-scale monochrome. Differences in ratings across these conditions indicate that hue carries additive information over that available in other skin cues (e.g. texture and tone) and that this aids discrimination of individual men's quality, especially in judgments of skin condition. We also found significant sex and age effects on discrimination. Our results are consistent with findings from other species that color cues can signal underlying quality and that sexual selection may have contributed to the evolution of color vision in primates.

“…The consistent answer is that they are (Osorio & Vorobyev 1996;Regan et al 2001;Parraga et al 2002). However, model computations also show that there are other classes of critical behaviours, for example discrimination of edible foliage or of variations in skin coloration, which would be similarly well served by the M/L dimension of primate colour vision Changizi et al 2006). So far, it appears that model studies alone are incapable of clearly identifying those aspects of primate life that impacted the evolution of their colour vision.…”

Colour vision allows animals to reliably distinguish differences in the distributions of spectral energies reaching the eye. Although not universal, a capacity for colour vision is sufficiently widespread across the animal kingdom to provide prima facie evidence of its importance as a tool for analysing and interpreting the visual environment. The basic biological mechanisms on which vertebrate colour vision ultimately rests, the cone opsin genes and the photopigments they specify, are highly conserved. Within that constraint, however, the utilization of these basic elements varies in striking ways in that they appear, disappear and emerge in altered form during the course of evolution. These changes, along with other alterations in the visual system, have led to profound variations in the nature and salience of colour vision among the vertebrates. This article concerns the evolution of colour vision among the mammals, viewing that process in the context of relevant biological mechanisms, of variations in mammalian colour vision, and of the utility of colour vision.

“…The evolution of red colour is also linked to gregarious social systems, which may facilitate the comparison of competitors (Fernandez & Morris, 2007). Interestingly, primate colour vision is near optimal for discriminating bloodrelated changes in skin colour (Changizi, Zhang, & Shimojo, 2006), although the evolution of trichromacy preceded that evolution of red skin (Fernandez & Morris, 2007).…”
