I don't know.

ooh is one that yellow/black one you had on in the sim, that looked cool. how about a black/pink one?

^ I'd like to see a pink one :D
As for the second color, how about Black like normal, but with multicolor/rainbow gradient where the solid color would be

Altus wanted one that Black and Gold, preferably with some glowy things. If you have the Texture sets already, you can easily churn those out.

Really just any 2 or 3 colors can make a decent scheme.
let me in on it so i can promote it when you do.

There's other designs i wanted to do with rings and spotty things too, i don't think it would fit with the myth set.
