IB is India Blue and considered a color, Cameo, Peach, violet, and Purple are sex-linked colors. Non-sexlinked colors include Opal, Bronze, Montana, and there may be more I can't recall right now. Then there are semi-sex-linked colors like Taupe, Mocha, Hazel, and a few others that are a combination of sex-linked colors and regular mutation colors.
