Traditional color vision theory posits that three types of retinal photopigments transduce light into a trivariate neural color code, thereby explaining color-matching behaviors. Thisprinciple of trichromacy is in need of reexamination in view of molecular genetics results suggesting that a substantial percentage of women possess more than three classes of retinal photopigments. At issue is the question of whether four-photopigment retinas necessarily yield trichromatic color perception. In the… 
Re-assessing perceptual diagnostics for observers with diverse retinal photopigment genotypes
Jameson et al. (2001) found that color perception differences are associated with photopigment opsin genotype, and they suggest that some standard color vision assessment methods may not be appropriate for assessing the perception of retinal tetrachromats (that is, female heterozygotes).
Photopigments and the dimensionality of animal color vision
Art, interpersonal comparisons of color experience, and potential tetrachromacy
This work empirically investigated color perception in genotyped individuals with a potential for greater than three retinal photopigment classes compared to controls, and investigated both professional artists and non-artist participants using psychophysical designs that employed low-level motion processing of isoluminant color stimuli.
Human Color Vision and Tetrachromacy
This Element focuses on new knowledge about the linkages between color vision genetics and color perception variation and the color perception consequences of inheriting alternative, nonnormative, forms of genetic sequence variation.
A Quantitative Theory of Human Color Choices
A quantitative model of a lexicographic semiorder type is created, which shows how different perceptual and cognitive influences can trade-off when making color similarity judgments, and concludes that distance in a CIE model is but the first of several layers in a hierarchy of higher-order cognitive influences that shape color triad choices.
Sex-related differences in peripheral human color vision: a color matching study.
Female showed substantially less saturation loss than males in the green-yellow region of color space, and it is speculated that this advantage of female over male color vision is conferred by M-cone polymorphism.
Modeling color percepts of dichromats
Signatures of selection and gene conversion associated with human color vision variation.
Nucleotide sequence analyses and tests of neutrality for a 5.5-kb region of the X-linked long-wave "red" opsin gene (OPN1LW) in 236 individuals from ethnically diverse human populations suggest that subtle changes in L-cone opsin wavelength absorption may have been adaptive during human evolution.
Sex-related differences in chromatic sensitivity
Assessing the performance of 150 males and 150 females on the color assessment and diagnosis (CAD) test found differences between males and females in red-green (RG) color discrimination may be related to the heterozygosity in X-linked cone photo pigment expression common among females.
Quantifying variations in personal color spaces: Are there sex differences in color vision?
We report a search for group differences in color experience between male and female subjects, focusing on the relative prominence of the axes of color space. Dissimilarity data were collected in the


Polymorphism of the long-wavelength cone in normal human colour vision
Evidence for the existence of two different long-wavelength cone mechanisms in normal humans is reported and the different patterns of colour matches made by male and female subjects indicate these two mechanisms are inherited as an X-chromosome linked trait.
More than three different cone pigments among people with normal color vision
Polymorphism in red photopigment underlies variation in colour matching
It is reported that a common single amino-acid polymorphism at residue 180 of the X-linked red visual pigment explains the finding of two major groups in the distribution of colour matching among males with normal colour vision.
Evaluation of single-pigment shift model of anomalous trichromacy.
Calculation of the r-g opponent chromatic channel can provide correct predictions of the spectral loci for unique yellow for anomalous trichromats.
New observations concerning red–green color defects
Family studies reveal that intrafamilial variability in chromatic discrimination is less than interfamilial variation, and a possible interpretation is that multiple, rather than three or four, alleles may be involved in X-chromosomal color-vision defects, with the alleles determining the proportion of functional anomalous cones.
The Emergence of Color Cognition from Color Perception
Reporting isomorphism between the perception and cognition of color, this article speculates upon how the two might interrelate and how that relation might be constrained. A pilot study of color
The arrangement of the three cone classes in the living human eye
Adaptive optics and retinal densitometry are combined to obtain the first images of the arrangement of S, M and L cones in the living human eye, allowing the sharpest images ever taken of the living retina.
A Measurement of the Adaptation of Color Vision to the Spectral Environment
An exploratory factor analysis of the reflectance spectral distributions of a sample of natural and man-made objects yields a factor pattern remarkably similar to psychophysical color-matching
