multicolored skin
When a character has two or more distinct colors making up their layer of skin. All skin colors present should be tagged, if possible.
This doesn't include naturally occurring differences in colors such as areolae, nipples, bruises, tan and blushing to name a few. At least one of the skin colors has to be unnatural and the colors have to be visually distinct from each other.
For instance, Danbooru post #4438684 has blue skin and yellow skin divided evenly on her flesh.
