Crayola released a set of multicultural crayons on 1992 with a more inclusive set of skin tones. While it did give children more choices than the original pink skin tone, and overall had a good reception. it was still met with some criticism since it was only a set of 8 colors.
All 8 colors in the multicultural colors set came from other sets. None are exclusive to this set.
