kin-me gin-me 金目銀目

In Japanese, kin-me gin-me 金目銀眼, "gold eye, silver eye," means a specific type of heterochromia: having one yellow eye and one blue eye.

Character: Amanojaku 天の邪鬼
Anime: Ghost Stories, Gakkou no Kaidan 学校の怪談 (Episode 1)

The reason for such an oddly specific term to exist is that this sort of heterochromia is particularly common in cats and dogs. In anime, cat girls also tend to feature this trait.
