I like the stone on the first picture and I think it would work with your scheme

My advice is don't do a gray and white kitchen. That ship has sailed.

@cpaul1 - if gray and white are going out, do you have thoughts on what's coming in? (interested seroiusly, not being snarky)

If you can afford to change up your style often, go with the trends. If not, try to stay timeless, so you can accessorize and paint on trend. That’s how I roll, it has worked for me.

If the ship has sailed for gray and/or white kitchens then someone needs to tell Houzz (and the interior designers posting photos) that the majority of the kitchens shown on here are out of date. Seriously that is practically all I see on here, including the newly posted photos. Is your question only about wall color and whether Revere Pewter works with your selections?

Be forewarned that trying to mix a lot of different grays/greiges is going to end up making at least one of them look purple, blue, or green. BTDT. Given that, however, Revere Pewter is a nice color in good lighting. It's undertones can be green in darker spaces as it was in my MIL's basement. SW Agreeable Gray is another greige I've had success with in my home but it's also highly light dependent.

I agree with shead and would add that since you have a lot of gray already in your kitchen, I would paint the walls white (test out a few whites to find one that looks good with your cabinets) to keep it from going too gray.

Alternatively (if it is not too late to make changes), I would actually prefer running the wood from the other room into the kitchen. That would add nice warmth to the room, give it a more classic feel, provide continuity between the rooms, prevent a possible design clash between your floors and counters (although I like both selections I am not sure I like them together), and would allow you to go gray on the walls without it looking dreary.

I have seen a white kitchen with white countertop and the island was a natural wood. it actually was very cool, and looked great!

I hate to be the bearer of truth but when you ask a quesron on here you often get info about other choices that might not be right.It is kind o like asking do you like these shoes but you don’t say what you are going to wear with them . All these elements need to work together and my 2 cents is that you would be better off to have the wood floor in the kitchen
