I'd probably do the opposite. Leave the cabinets and counter and change the floor. the cabs /counter and appliances together have a chance at looking good with a new floor. the floor you have has a cocoa / and gray/ and whitish tone...that probably is leading you to think about gray cabinets. But that is not a good route overall. Change the floor. Looks like some blank wall space over on the left...think about a small hutch/bakers rack/serving counter [cart]...something like that to add in something for use and to bring detail into your space.

slate look floors always work w maple cabs and black counters: there are various ones avail in the vinyl products. [lighter walls would help..when you can]

I find this one cheery and interesting w the backsplash they picked also.

Thank you for the ideas. I really like your ideas for the blank wall I have. Unfortunately the tiles have to stay. Changing them is not an option. Countertop is green and cabinets are 20 yrs old and so we need to change.
