Just wanted to second the_rotten1's Fauna link. Perusing breeders on there can give a really good idea of not only what's available, but also who might be working with something you'd like. There are several Rosies up right now, include some pretty vibrant ones. If orange is your thing, there are selectively bred lines of locality animals that really bring it out. If locality doesn't matter, an albino or hypo Rosy might be what you're looking for.
