My blue eyes will forever be real to me! But was told blue are colorless but this video says there's brown underneath? So confused... The color of your eyes depends on how much of the pigment melanin you have in your iris—the colored part of your eyes. The more pigment you have, the darker your eyes will be. Blue, grey, and green eyes are lighter because they have less melanin in the iris. The iris is usually strongly pigmented, with the color typically ranging between brown, hazel, green, gray, or blue. Occasionally, the color of the iris is due to a lack of pigmentation, as in the pinkish-white of oculo-cutaneous albinism, or to obscuration of its pigment by blood vessels, as in the red of an abnormally vascularised iris. Despite the wide range of colors, the only pigment that contributes substantially to normal human iris color is the dark pigment melanin. The quantity of melanin pigment in the iris is one factor in determining the phenotypic eye color of a person. Structurally, this huge molecule is only slightly different from its equivalent found in skin and hair. Iris color is due to variable amounts of eumelanin (brown/black melanins) and pheomelanin (red/yellow melanins) produced by melanocytes. More of the former is found in brown-eyed people and of the latter in blue and green-eyed people. en.wikipedia.org/wiki/Iris_(anatomy)#Eye_colorWelcome to Brownistan/Brownland/Brownia!  |
