I wouldn't worry about the pattern of the UbaTuba at all, it's a pretty dark stone and will work with amost anything you put in there. We have Verde Peacock which is in the same family as the Uba Tuba, I don't have an island, but if I did, I would DEFINATELy put a different color on it because I think it would add interest to the room. We're doing our bathroom right now and found a slab called Golden Shore, I'm sure the store made the name up, but it closely resembles Golden Beach, and like the Bordeaux, it has tiny purplie maroon dots in it too, lovely

If you're having a hard time visualizing it, ask for a sample and bring it home to test.

I think as long as it's a clearly different colour and on a distinct piece of cabinetry, it will work. That usually prevents it from looking like it was an oops.
