Brown, Grey and Blue eyes= Varied % of Eumelanin
Green eyes = 100% Pheomelanin 0% Nigger tier Eumelanin
Eumelanin
Part of the structural formula of eumelanin. "(COOH)" can be COOH or H, or (more rarely) other substituents. The arrow denotes where the polymer continues.
Eumelanin polymers have long been thought to comprise numerous cross-linked 5,6-dihydroxyindole (DHI) and 5,6-dihydroxyindole-2-carboxylic acid (DHICA) polymers.[7]
There are two types of eumelanin, which are brown eumelanin and black eumelanin. Those two types of eumelanin chemically differ from each other in their pattern of polymeric bonds. A small amount of black eumelanin in the absence of other pigments causes grey hair. A small amount of brown eumelanin in the absence of other pigments causes yellow (blond) hair. As the body ages, it continues to produce black eumelanin but stops producing brown eumelanin, resulting in the grey hair that is common in elderly people.[8]
Pheomelanin
Part of the structural formula of pheomelanin. "(COOH)" can be COOH or H, or (more rarely) other substituents. The arrows denote where the polymer continues.
Pheomelanins (or phaeomelanins) impart a range of yellowish to reddish colors.[9] Pheomelanins are particularly concentrated in the lips, nipples, glans of the penis, and vagina.[10] When a small amount of brown eumelanin in hair, which would otherwise cause blond hair, is mixed with red pheomelanin, the result is orange hair, which is typically called "red" or "ginger" hair. Pheomelanin is also present in the skin, and redheads consequently often have a more pinkish hue to their skin as well.
In chemical terms, pheomelanins differ from eumelanins in that the oligomer structure incorporates benzothiazine and benzothiazole units that are produced,[11] instead of DHI and DHICA, when the amino acid L-cysteine is present.
