The main pigment that gives color to the skin and hair Melanin produces eumelanin and phaeomelanin
Melanin is a dark substance in the skin, eyes, and hair of people and animals, which gives them colour and can protect them against strong sunlight. a natural dark brown colour in human skin, hair, and eyes (melas + -in chemical substance). Any of several organic compounds, dark biological pigments that give coloration (shades of yellow to brown) to skin, hair, feathers, scales, eyes, and some internal tissues, notably the substantia nigra in the brain. In humans, melanins help protect the skin against the damaging effects of ultraviolet radiation, but melanoma may arise from cells that produce it. The amount in the skin depends on both genetic and environmental factors. Melanin is produced from the amino acid tyrosine; albinos lack the enzyme that catalyzes that reaction (see albinism)
