Since your trim is dark it complements "A" .

IMO you need to provide more info but generally no more than 2 finishes in a kitchen works best. So a different island counter with all the same cabinets or all the same counters with the island cabinets a different color. I think walnut and high gloss white are a beautiful combo and I have to say I do not like the gray with the wood at all. I aslo do not like the cabinets around the window either IMO you need a good KD
