Pictures of the room may help.

You could use daylight spectrum lighting, to make the light color more uniform.

North and south exposure, go with a greige undertone. As for your floor, gunstock oak, there are several different tones from several different brands. I chose this floor:

Using a greige, which I know works with north/south exposure , try Elmira White on the wall and Glacier on the cabinets.

Any color you go with is going to look different in different ends of your kitchen with different amounts of light. I'm a fan of Maritime White in your lighting situation and with your floors, but you said you want a color and not white. For a change could you go with a beige, greige and use counters and tiles as your new change element?

Thank you all! I guess you confirmed that the less saturated, greige colors work best in terms of color stability, but I really don't want to go that way. But @John Liu comment made me think, and I believe that the north side will have artificial lighting most of the time anyway, at least while cooking, so if I go with something that looks good under the sun, I can live with how it looks by the north windows. I am also testing another, darker, blue-green paint today. Maybe more pigment will mean that it doesn't get washed out by the sun that easily. I know there will be a change, but hopefully it won't turn into yellow .

Make sure your light bulbs are all led 3500 or 4000. I think 4000 daylight type bulb would help you out a lot, so you are not getting all these golden tones. I have used the color in this link in different lighting conditions, and it has worked quite well. https://www.myperfectcolor.com/paint/423093-sherwin-williams-hgsw1326-blue-iris Since you mentioned a blue green, I thought this one might interest you, since its a nice clear color with no graying dirty tones.

Olgala- I have a similar problem with lighting in my kitchen. I chose Sherwin Williams Rivers Edge for my cabinets. Yes, it looks different at either end of kitchen, but I think it’ll work fine. (The painters are painting it now.)

What's the style of the home? Are you traditional, a bit more modern....what? What is the door/drawer style on the cabinetry? What does the current kitchen look like, and what is the is the kitchen cabinetry /appliance PLAN in a drawing? What is the appliance finish? What is your countertop or it isn't selected?

You have nowhere NEAR enough information, to answer your question.......so return same thread with a lot more information in comment boxes below.

Kitchens have artificial light most of the time I like LED 4000K for this exact issue . I dislike greige type colors to me they always look ,like you could not decide on gray or beige . I use this color a lot for this type of lighting I cut it 25-50% often to get the shade just right fo the space it is a BM color so any white ythat works with thta might be the answer . Maybe use Steam for the cabinets also BM

I went to some stone yards in the last few days, and I just didn't like any Taj Mahal slabs. So I am down to blacks. Most likely something like honed Black Mist.

And after all the tests, I am seriously considering painting the coffee bar darker.

These are the two colors I think will work. I have an old door I painted Mediterranean Teal, and I haven't yet got a chance to pick up a Healing Aloe sample for the main kitchen area, but online it seems like a good match. And Mediterranean Teal, while looking different in the sun, doesn't turn yellow like lighter colors for me. At the same time I am not sure I want the entire room this dark, especially with the floor-to-ceiling pantry doors and dark counters.

Is it going to look fine?
