Oddskin

In the English language, the word oddskin is an ethnic slur typically directed at multicolored humans.

It was used derogatorily, and by the mid-20th century, particularly on Earth, its usage by non-multicolored humans became unambiguously pejorative, a racist insult. Accordingly, it began to disappear from general popular culture. Its inclusion in classic works of literature has sparked modern controversy.

It would be different from anti-African racists or anti-Asian racists
