I would say Heterochromia and Eye color is a Justify or omit.

For instance, if you have a character whose eye color is important, it could be because they are blind in one eye, or a bad guy believes in a "superior race", or they have a false eye, or a friend's(like Kakashi... only less magical) or a special semblance use color.
