I'm pretty sure that the 2011 models had two different stain colors, Light Oak and Dark Cherry.
I would suggest that you take a drawer or cabinet drawer in to a paint store and they can match it.
I don't know if you can get those colors today and I don't know if you could get an unfinished island.
Your best bet would be to call the factory and ask your questions.
Have your VIN handy. It can be found on a yellow sticker on the door jamb, your title or the outside wall near the front off door side.
