Eye colors can range from the most common color, brown, to the least common, gray. Rare genetic specialties can even lead to unusual eye colors: black, red, and violet. Eye color is an inherited trait influenced by more than one gene.Three main elements within the iris contribute to its color: the melanin content of the iris pigment epithelium, the melanin content within the iris stroma, and the cellular density of the iris stroma. In eyes of all colors, the iris pigment epithelium contains the black pigment, eumelanin. Color variations among different irises are typically attributed to the melanin content within the iris stroma.





The eyes of a person with albinism may appear red under certain lighting conditions due to the very low quantities of melanin. ';True'; red eyes also exist in albinistic and even some non-albinistic populations, but are very rare. Only about 20 cases of natural red eyes are recognized throughout the world. Red eyes are caused by the complete lack of pigment in the iris leaving the blood vessels as the only visible part of the iris, or a blood leakage into the iris.What genetics cause eye color?
Sounds like you're a bit albinic.
