I can't tell if that left side is connected to anything or not. I am guesseing not since the op syas "island". If it is an island it needs one receptacle to the left and one to the right of the sink. The one in the end cabinet would not be required.
This is where good electricians are seperated from really good electricians. I would get receptacles to match the colors as close as possible. White would not be it.
