To explain the surprisingly high frequency of congenital red–green colour blindness, the suggestion has been made that dichromats might be at an advantage in breaking certain kinds of colour camouflage. We have compared the performance of dichromats and normal observers in a task in which texture is camouflaged by colour. The texture elements in a target area differed in either orientation or size from the background elements. In one condition, the texture elements were all of the same colour…

Advantage of Dichromats over Trichromats in Discrimination of Color-Camouflaged Stimuli in Humans

TLDR
Results suggest that participants with color-vision deficiency may have a superior visual ability to discriminate the color-camouflaged stimuli.

Advantage of dichromats over trichromats in discrimination of color‐camouflaged stimuli in nonhuman primates

TLDR
It is demonstrated that dichromatic nonhuman primates possess a superior visual ability to discriminate color‐camouflaged stimuli, and that such an ability may confer selective advantages with respect to the detection of cryptic foods and/or predators.

Color Perception in Protanomalous Female Macaca fascicularis

TLDR
The experiments show that protanomalous macaques can break color camouflage, similar to dichromats, and can discriminate colors similarly to trichromats.

Experimental evidence that primate trichromacy is well suited for detecting primate social colour signals

TLDR
It is suggested that primate trichromatic colour vision confers excellent ability to detect meaningful variation in primate face colour, consistent with the hypothesis that social information detection has acted on either primate signal spectral reflectance or photoreceptor spectral tuning, or both.

Color vision test for dichromatic and trichromatic macaque monkeys.

TLDR
Comparison studies of color vision employing similar tests may be feasible to examine the difference in color behaviors between trichromatic and dichromatic individuals, although the genetic mechanisms of trichromeacy/dichromacy is quite different between new world monkeys and macaques.

Number of discernible colors for color-deficient observers estimated from the MacAdam limits.

TLDR
Complementary estimates obtained for the spectral locus of monochromatic stimuli suggest less impairment for color-deficient observers, a fact that is explained by the two-dimensional nature of the locus.

Dichromatic and Trichromatic Callithrix geoffroyi Differ in Relative Foraging Ability for Red-Green Color-Camouflaged and Non-camouflaged food

TLDR
There is no significant difference between dichromats and trichromats for either camouflaged or non-camouflaged Kix®, though the power in the tests is low because of high individual variation.

Color discrimination, color constancy and natural scene statistics

Does the visual system allocate discriminative ability to different regions in colour space in a way that optimizes discrimination among natural colours? If so, discrimination should satisfy a " cube

Relative advantages of dichromatic and trichromatic color vision in camouflage breaking

TLDR
Online camouflage games reveal trichromats are better at finding birds and eggs than simulated dichromats, but dichromat can learn faster, and they learnt to capture eggs faster.

TLDR
It is argued that the colour vision of man and of the Old World monkeys depends on two subsystems that remain parallel and independent at early stages of the visual pathway, and that the New World monkeys have taken a different route to trichromacy.

Variations of colour vision in a New World primate can be explained by polymorphism of retinal photopigments

TLDR
Good quantitative agreement was found when the microspectrophoto-metrically measured absorbance spectra were used to predict the behavioural sensitivity of individual animals to long wavelengths and suggests that the behavioural variation arises from variation in the retinal photopigments.

Interference and dominance in texture segregation: Hue, geometric form, and line orientation

TLDR
Findings support Beck’s (1982) model of textural segmentation and call into question traditional notions of the preattentive stage of perceptual processing.

Contrast dependence and mechanisms of masking interactions among chromatic and luminance gratings.

TLDR
The spatial-frequency selectivity of the luminance-facilitates-color interaction is much broader than facilitatory interactions in either the color-color or Luminance-luminance conditions, which is consistent with models that invoke inhibitory or more elaborate excitatory masking interactions.

Visual texture segregation based on orientation and hue

TLDR
The results clarify why different line orientations provide different effectiveness in texture segregation, and suggest that both interstimulus confusability and intrastimulus stability properties determine the ability of a dimension to interfere with, or to be interfered with by, another dimension in texturegregation.

Unequal crossing over in the ribosomal DNA of Saccharomyces cerevisiae

TLDR
The frequency of unequal crossing over, as measured by the deletion or duplication of an inserted genetic marker (LEU2), is sufficient to maintain the sequence homogeneity of the rDNA repeat units.
