The simulations highlight the role that known processes of adaptation may play in compensating color appearance for variations in sensitivity both within and across observers, and provide a novel tool for visualizing the perceptual consequences of any variation in visual sensitivity including changes associated with development or disease.

Though nothing is known, these signals presumably interface with motor programs and emotional centers of the brain to mediate the widely acknowledged emotional salience of color.

The results of this study provide evidence for compensatory amplification, but suggest that the degree of compensation varies across individuals.
Orthogonal Relations and Color Constancy in Dichromatic Colorblindness
- BiologyPloS one
- 2014
Previously published data on dichromacy are plotted and analyzed in CIELUV uniform color space to find spatial relations in terms of color appearance space, and Wavelength shifts between illuminants demonstrate chromatic adaptation correlates exactly with that in trichromatic vision.
The dimensionality of color vision in carriers of anomalous trichromacy.
- BiologyJournal of vision
- 2010
It is suggested that most carriers of color anomaly do not exhibit four-dimensional color vision, and so it is believed that anomalous trichromacy is unlikely to be maintained by an advantage to the carriers in discriminating colors.
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.
Compensation for red-green contrast loss in anomalous trichromats.
- BiologyJournal of vision
- 2014
The contraction along the L/(L + M) axis shown in the perceptual color spaces of anomalous trichromats is far smaller than predicted by their reduced sensitivity, suggesting that an adaptive adjustment of postreceptoral gain may magnify the cone signals of anomalies to exploit the range of available postreceptionoral neural signals.

This study concluded that RTs are suitable for detecting temporal differences in color processing but, for that very same reason, rather ill-suited for reconstructing color spaces, and that the rating procedure yielded the most logical results for recovering color space.

The discriminability of 66 pairs of colors was quantified by measuring the time that observers needed to judge whether the two colors in each pair were the same or different. A multidimensional…
Chromaticity diagram showing cone excitation by stimuli of equal luminance.

A plane of constant luminance provides a chromaticity diagram in which excitation of each cone type is represented by a linear scale (horizontal or vertical), and in which the center-of-gravity rule applies with weights proportional to luminance.

The cone fundamentals for X-chromosome-linked anomalous trichromats for the wavelength range of 400-700 nm were derived and it was found that the protanomalous M- and L'-cone pigments are separated by 10 nm and the deuteranomalously M'- and L-cone piglets are separatedBy 6 nm, where M and L indicate middle- and long-wavelength sensitive, respectively.

The fact that no bias was observed in the results of the triads-ratio judgments suggests that this procedure is the more appropriate technique for scaling color relations.
