I don't know what Revere Pewter would look like with the browns you have, but I've seen pictures of it with walnut and calacatta marble and it look very nice. Buy a sample and paint a board with several coats and set it in the room to see if you like it. It is a Benjamin Moore color.

@Katie B. we put a large piece of black paper there to get an idea, but it was too severe. We also will be mounting a flat screen TV in the space as well. So if not black, which one?

Simply White in flat looks a little different than Simply White in semi-gloss. Are your cabinets semi-gloss or eggshell/satin? The difference in sheen changes our perception of the color. My point being you could just paint the walls Simply White and there will be some contrast. If you want more contrast, look at Floral White OC-29 and Soft Chamois OC-13. Soft Chamois for me is a little too bright in a south facing room but brightens up rooms with different exposures. As with all paint, the only way you're going to know what is going to work in your space is to sample.

That is a lovely kitchen. Thanks for posting it. On my monitor the cabs and walls look to be slightly different. The walls seem to have more colour to them than the cabs. A nice BM white for cabs is Steam in the aura line and off-whites that seem similar to the walls in the pic might be something like French Canvas or Old Prairie.
