Yes, I had more or less come to that same conclusion. The cabinets are staying so I may just have to count on the floors and that slate backsplash to be my warming factors. I'm not quite sure what to paint those walls as I'm still quite anti white.

Maybe consider a light sage green?

Any way you could get that gray cabinet glazed to tone it down. It’s more blue than gray.

You need someone with design taste to help you onsite. What you have going on there looks like a mess to me of too many dark colors and forcing things to match. And then I would not introduce another color like green.

NO glaze and a soft sage green looks awesome with the slate and the gray.

I personally do not care for walls painted a color that has nothing to do with anything else. With that scheme I would find a paler gray than the cabinets. That also will compliment the trim wood. With such a dark scheme I hope there will be a lot of really good lighting of various types which will be much needed during a MI winter.

We have a lot of large windows in our new addition, very very light. This is why I've chosen to pull in some darker richer colors.

The scheme looks very nice but samples look very different from full walls of dark color on cabinets and backsplash. Daylight is very different in summer and winter when days are so short. Then there is evening. With that type of scheme I would be looking at general ceiling lighting and under cabinet lighting at the least. If no one has mentioned this before it's something to keep in mind. Big windows are wonderful and always a bonus, of course.

The problem is the undertones - cabinet is blue-toned gray and clashes with the warm-toned grays of the other pieces; they just don't go together.

Thanks for the thoughts. Much appreciated. Some things you can see in your head, but when it comes to reality, you realize it's simply not going to work. I like the light gray idea. I think some of the color nuances get lost in Iphone photos, which is why I deleted the photo. Our house is extremely light, lots of large windows and tall ceilings. I do not think "too dark" is going to be a factor. No triggers have been pulled yet on anything except for the cabinetry and the trim, all of which we love. The gray cabinets are just proving to be a bit of a challenge to work around when trying to keep things on the warm side.

The sun goes down and most of the dinner prep and schoolwork is after dark. Especially in winter. When big windows turn into giant black holes. Not sources of light. You have to plan on a LOT of additional lighting with your choices or it’s going to be a cave in the evenings.

The cabinets need to be repainted a much warmer and lighter color. They just do not work with your other choices.

We have an adequate amount of lighting. The "light gray" cabinetry is in my large laundry room, also adequately lit. My original question was just whether a person could paint a warmer color on the walls with gray cabinets. I'm coming to the conclusion that I really can't pull that off.

^^ No, probably not. IME natural light causes undertones to be more pronounced.

Colors are distorted both in phones and in photos. No one is trying to pick a paint color based on the photo LOL. I would have left the photo up if only to see what other comments were made. I know it can be very annoying when you've taken a decision and folks raise what seem to be issues that don't apply. Sometimes the off comment can be unexpectedly useful OTOH.

For me, the scheme you showed is dark but not warm. It's mostly gray -- cool -- with some warm accents. IMO the best way to keep the lovely cabinets looking integrated with the rest of it is to make the walls lighter than cabinets so there is a tone-on-tone effect but not so pale that the cabinets pop visually. Warm would be tail wagging dog I think.
