If you're keeping the cabinet color, floor, and counters, embrace the cabinets' peachy tones with something like BM Parchment. Help all those different shapes on the walls and ceilings flow. White and black already provide a lot of contrast to the peachy toned cabinets (too much, IMO).

Or look at Sparkling Wine, Navajo White, Mayonnaise.

Or if you are still set on the contrast, try Ocean Air.

Better yet (IMO), paint the upper cabinets and walls a white that coordinates with the floor and appliances, probably Chantilly Lace. Then put your contrasting color on the lower cabinets, something like BM Caribbean Teal. Put colorful art above the stove and on the soffit where the clock is. Maybe 3 or 5 same-size black frames.

I'd find the right white for your whole kitchen and ceiling.

- Remove the trim piece above your stove. It will really help the space feel less enveloped in the peachy wood color.

- Get a white ceiling light so it disappears. Swap out the black clock, get canisters, and towels that all coordinate and are your beachy tropical vibe so you have a focal point for the eye to go to that isn't just the cabinets.

I think Manchester Tan and Sweet Celadon are both too much color. I would not do another white, but would try some colors that on the samples will look grayer, more muted than what you think is pretty, but once you paint an entire wall the color always is more vibrant than when you are looking at a small sample.

I think you like many of the colors that I like (teal, purples, reds)(Art on fridge, drying mat, teal exterior and the mailbox art on the wall), and the oak cabinets are going to challenge this palette, but it can work.

Here are a couple of pics where I muted the green on your walls using orange or gray overlays

This photo I overlaid with the purple on your fridge art - creating a taupe.

Most people are a bit afraid of taupe with oak and it is a bit tricky to get the right shade. But taupe really is just orange mixed with gray, so it does have the same hue as your oak cabinets.

I could only find one photo of a home with taupe back splash and a taupe that leans gray on the walls with wood cabinets, but it shows you what it may look like IRL

I would probably start with a color like BM Grege Avenue or Evening Gown and then move grayer or more beige till I got it just where I wanted.

thanks for the comments. with everything considered I think Im going to go the off white direction. I want a more airier and lighter color. Thanks!
