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…

Photosensitive and photostable pigments in the retinae of Old World monkeys.
TLDR
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.
Visual Pigments and Colour Vision in Primates
TLDR
A number of questions still remain concerning the number and spectral location of visual pigments in man, both in normal observers and in anomalous trichromats.
Alouatta Trichromatic Color Vision: Cone Spectra and Physiological Responses Studied with Microspectrophotometry and Single Unit Retinal Electrophysiology
TLDR
Recording from retinal ganglion cells of the same animals used for MSP measurements found MC cells and PC cells in the Alouatta retina with similar properties to those previously found in the retina of other trichromatic primates.
Cone pigment polymorphism in New World monkeys: Are all pigments created equal?
TLDR
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
TLDR
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.
Human Color Vision
TLDR
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

TLDR
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.

The visual pigments of rods and cones in the rhesus monkey, Macaca mulatta.
TLDR
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.
Microspectrophotometric demonstration of four classes of photoreceptor in an old world primate, Macaca fascicularis.
1. Microspectrophotometric measurements reveal four classes of photoreceptor in the retina of the cynomolgus monkey, Macaca fascicularis, which is known to possess colour vision similar to that of a
Color vision in the spider monkey (Ateles).
TLDR
Spectral sensitivity and color vision were investigated in 2 spider monkeys (Ateles) using a forced-choice discrimination paradigm and indicated that at least two qualitatively different types of color vision exist among spider monkeys.
Behavioural and microspectrophotometric measurements of colour vision in monkeys
TLDR
Direct microspectrophotometric measurements are described on the eyes of two squirrel monkeys whose colour vision had been shown to differ behaviourally, consistent with classical explanations of abnormal colour vision.
Visual Pigments of Single Primate Cones
TLDR
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.
New wavelength dependent visual pigment nomograms
Recent results from single‐cell microspectrophotometry: Cone pigments in frog, fish, and monkey
TLDR
The bullfrog was found to have blue-absorbing cones in addition to other previously known photoreceptors in amphibians and preliminary data are presented on the four pigments in rhesus and cynomolgus monkeys.
Human visual pigments: microspectrophotometric results from the eyes of seven persons
TLDR
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.
