Can have slight brown or grey tinges. Can make the eyes a dark brown or black. Can change the hair to a dark brown or black or very dark shade of the natural base too.

A mix of two breeds.
If no parents are listed, the breeds must be the one listed and your choice of the other.
If parents are listed, the breeds must be the one listed and (one of) the other parent's breed that is not listed.

The mix can be a 50-50 split or favoring one breed over the other, but aspects from both breeds must show.

The centaurian is blind. Unlike simply giving your centaurian bad eyesight or making them "legally blind", the blind mutations means they cannot see a thing, they live in a black world.

An albino mutation. Makes your centaurian extremely pale or white. Can also be shown akin to leucism. Depending on the markings you can hide them or not show them. Can have slight pink or yellow/grey tinges. Can make the eyes a soft lavender, red, or pink. Hair can be light yellow/white/silver or a light shade of it's natural.

This centaurian cannot have offspring.

An albeit normal looking Centaurian, Infected Centaurians generally display some kind of disease of forms, whether that's large colored pockets of goop, some alien lifeform trying to get out of them, or body fluids leaking from their orifaces.

Mutated Centaurians are not normal looking. Sometimes being as little as being too small (The size of a house cat) or too large (The size of a 2 story house), or as much as their eyes popping out, having extra limbs, or their bones jutting in weird ways. Mutated Centaurians look very alien to normal Centaurians.

Cannot mutate the entire form to be unrecognizable as a centaurian, and must retain key aspects of their breed(s).

The centaurian is deaf. Unlike simply giving your centaurian bad hearing or making them "legally deaf", the deaf mutations means they cannot hear a thing, they live in a silent world.

This centaurian has parents that are closely related to each other. This could cause problems with breeding.
