I think if there is anyway to have some of the dark in the kitchen, like a dark island, it would tie it all together. I think something has to tie it together, it might not even need to be that extreme. Perhaps a dark kitchen table, or a dark piece of freestanding furniture.

I have white perimeter cabinets, with a dark island as well as dark pantry cabinets surrounding my fridge. I would have no problem putting dark cabinets in the adjoining family room.
