The squirrel monkey (Saimiri sciureus) exhibits a polymorphism of colour vision: some animals are dichromatic, some trichromatic, and within each of these classes there are subtypes that resemble the protan and deutan variants of human colour vision. For each of ten individual monkeys we have obtained (i) behavioural measurements of colour vision and (ii) microspectrophotometric measurements of retinal photopigments. The behavioural tests, carried out in Santa Barbara, included wavelength…

Microspectrophotometric measurements of retinal receptors are reported for eight species of Old World monkey, finding that the trichromacy of frugivorous catarrhine monkeys may have co-evolved with a particular class of coloured fruit.

The inequality of opsin gene frequency in Callitrichid monkeys may reflect adaptive pressures and alter the relative representation of the three possible dichromatic and trichromatic phenotypes.
Protein Limitation Explains Variation in Primate Colour Vision Phenotypes: A Unified Model for the Evolution of Primate Trichromatic Vision
- Biology

Primates have an additional colour channel enabling trichromatic vision via a duplication and divergence of the L opsin gene, resulting in long and middle wavelength-sensitive photopigments, which permits enhanced discrimination of light and perception of different shades of green, yellow, orange and red.

Red-green color blindness is not associated with loss of acuity, although this is present in a rare form of dichromacy called Bornholm eye disease where cone dysfunction and myopia is also present, and the recessive disorder of achromatopsia where all cone classes may be absent.
THE DISTRIBUTION AND NATURE OF COLOUR VISION AMONG THE MAMMALS
- BiologyBiological reviews of the Cambridge Philosophical Society
- 1993
This review has evaluated the proposition that relatively few mammalian species have a capacity for colour vision in mammals in the light of recent research on colour vision and its mechanisms in mammals and concluded that the baseline mammalian colour vision is argued to be dichromacy.

If the long wave‐length and middle wave-length cone pigments of the rhesus monkey are assumed to be identical to those of man and if additional assumptions are made about the lengths of human outer segments and about prereceptoral absorption, it is possible to derive psychophysical sensitivities that closely resemble the pi5 and pi4 mechanisms of W. S. Stiles.

The commonly held belief, for which there has previously been no direct and unequivocal evidence, that color vision is mediated by several kinds of receptors (possibly three), each containing photopigments absorbing in diflerent regions of the spectrum, is confirmed.

Both patients were classified as normal trichromats by all clinical tests of colour vision but there was a clear difference in their relative sensitivities to long-wave fields, which proved to be that required by the microspectrophotometric results.
