I'm not overly familiar with BRB's, but it doesn't look like a normal to me. Blacks might be a bit too dark to be hypo, but I would say there is definitely something going on there.
I have been doing a bit of research and it seems there have been a few breeders prove out some anery lines. But this doesn't really look like any of the new anery's to me.
I don't think there are too many BRB keepers on this forum, but hopefully someone will chime in.
