The irises of human eyes exhibit a wide spectrum of colours. Eye color is a polygenic phenotypic trait determined by two factors: the pigmentation of the eye's iris [1] [2] and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. [3]: 9
The RGB color model, therefore, is a convenient means for representing color but is not directly based on the types of cones in the human eye. The peak response of human cone cells varies, even among individuals with so-called normal color vision; [8] in some non-human species this polymorphic variation is even greater, and it may well be adaptive.
People with lighter eyes also consume significantly more alcohol, as darker eyed people require less alcohol to become intoxicated. The reason boils down to genes.
Magenta is variously defined as a purplish-red, reddish-purple, or a mauvish–crimson color. On color wheels of the RGB and CMY color models, it is located midway between red and blue, opposite green. Complements of magenta are evoked by light having a spectrum dominated by energy with a wavelength of roughly 500–530 nm.
With brown eyes taking an overwhelming lead, all of the other eye colors have lower percentages. According to WorldAtlas , 8-10 percent of the world's population have blue eyes.
A color space maps a range of physically produced colors from mixed light, pigments, etc. to an objective description of color sensations registered in the human eye, typically in terms of tristimulus values, but not usually in the LMS color space defined by the spectral sensitivities of the cone cells.
The human eye's red-to-green and blue-to-yellow values of each one-wavelength visible color [citation needed] Human color sensation is defined by the sensitivity curves (shown here normalized) of the three kinds of cone cells: respectively the short-, medium- and long-wavelength types.
A single color doesn’t equal monotony. When green drenching a space, mix different hues of leaf colors, from chartreuse to olive green, and use a variety of leaf textures to keep the scene ...
