    Light skin is a human skin color that has a low level of eumelanin pigmentation as an adaptation to environments of low UV radiation. [ 1 ] [ 2 ] Due to migrations of people in recent centuries, light-skinned populations today are found all over the world.

    The green color is caused by the combination of: 1) an amber or light brown pigmentation in the stroma of the iris (which has a low or moderate concentration of melanin), and 2) a blue shade created by the Rayleigh scattering of reflected light. [29] Green eyes contain the yellowish pigment lipochrome. [53]

    en.wikipedia.org/wiki/Biological_pigment

    Pigmentation is used by many animals for protection, by means of camouflage, mimicry, or warning coloration. Some animals including fish, amphibians and cephalopods use pigmented chromatophores to provide camouflage that varies to match the background. Pigmentation is used in signalling between animals, such as in courtship and reproductive ...

    The Fitzpatrick scale has been criticized for its Eurocentric bias and insufficient representation of global skin color diversity. [9] The scale originally was developed for classifying "white skin" in response to solar radiation, [2] and initially included only four categories focused on white skin, with "brown" and "black" skin types (V and VI) added as an afterthought.

    Like all materials, the color of pigments arises because they absorb only certain wavelengths of visible light. The bonding properties of the material determine the wavelength and efficiency of light absorption. [5] Light of other wavelengths are reflected or scattered. The reflected light spectrum defines the color that we observe.

  9. Pigmentation disorder - Wikipedia

    en.wikipedia.org/wiki/Pigmentation_disorder

    Pigmentation disorders are disturbances of human skin color. [1] There may be a loss or reduction, which may be related to loss of melanocytes or the inability of melanocytes to produce melanin or transport melanosomes correctly. [1] Most pigmentation disorders involve the underproduction or overproduction of melanin. [2] [3]
