Heterochromia iridium

This is so random but I am so fascinated by people that have different colored eyes. I think it is cool because it is so rare. I have only encountered a handful of people that have them; apparently it is genetic (except David Bowie's eyes,which is a result of permanent dilation because he was punched in the eye)

according to Wikipedia

Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin.[2][3][4] The affected eye may be hyperpigmented (hyperchromic) or hypopigmented (hypochromic).[5] In humans, usually, an excess of melanin indicates hyperplasia of the iris tissues, whereas a lack of melanin indicates hypoplasia.
