First measure the walkway from the island counter to the fridge that needs to be at least 48”If you are doing the same cabinets for the island then IMO you can have a counter for the island that is more of a statement but if the island cabinets are going to be a different color IMO the counters should all be the same.

That island looks too big for the space. Have you actually measured the aisles? You can either do two cabinet colors and one countertop, or two countertops and one cabinet color. So if your island is going to bet he same as your permitted cabinets go ahead and do a statement countertop for it. If you're using a different cabinet color for the island do all of the countertops the same.
