Sorry but bubinga is an African wood similar to mahogany. My 12-string has bubinga back and sides and it looks like slightly dark mahogany. I wouldn't mistake it for rosewood in the dark.
I'm afraid you is both right. Bubinga also goes by the name "African Rosewood," even though it is not actually a rosewood. I don't think it looks particularly like rosewood or mahogany. If forced, I'd say it looks a little more like mahogany, but Bubinga's grain is sort of blob-like and a little bit arbitrary. Very dinstinctive stuff.
