How eye color works
Every eye color is the same two ingredients in different doses: melanin (brown-black pigment) and the iris structure that scatters light. Lots of melanin reads as brown. Almost none reads as blue or gray — those aren't pigments at all, but light scattering off nearly-empty tissue. The in-between amounts, sometimes with a golden pigment called lipochrome, produce green, hazel, and amber.
That recipe also sets the rarity ladder. Brown is the global majority. Blue covers roughly 8–10% of people, hazel about 5%, amber about 3%, green about 2%, and gray around 1%. Central heterochromia is a descriptive pattern without reliable population statistics, so it is not scored separately. Where you live changes the experience: green is unremarkable in Dublin and remarkable almost everywhere else.
