Are these tags worth keeping? What's the difference between an albino character and one with white fur/red eyes? Same goes for melanistic.

Reason: An albino human?

Albinism is notable for being present in humans. The "white body, pinkish eyes" is a distinctive look that is understood to mean "albino" even in furry art.

Melanism in furry art isn't much different from having all black fur/skin, which isn't particularly notable unless that species happens to be popular for the trait (e.g., black panther). It seems like black_fur/black_scales/etc. are probably preferred in this case.

Why isn't it called melano instead of melanistic? It fits perfectly with albino.
