I already said if Robert says it's a black pastel, then that's what it is.
However I voted "Other" on principal. Breed together they make the same super, they're the same thing to me. It's frustrating trying to learn when there aren't clear definitions and seven different names for the same thing. If you breed a blonde pastel to a lemon pastel to a jungle pastel, you get a super, but a black pastel makes a pewter. Why is it even classified as a pastel?
I choose science over marketing.
