I've tried doing my due diligence of reading up on my options and finding a few discussions both here and reddit before posting. Alas, since each space is different and I'm not good at this, here I am. I can provide links below to what I've read, though.

We're in the process of buying. Closing soon and, if possible, I'd like the kitchen, dining area, and living room to each have separate colors. I can live with keeping the kitchen its current color if that's the best suggestion, but the kitchen looks a bit boring to me right now.

The very very brief version of my questions:

-Can I even get away with 3 separate colors? Would you instead recommend one color only or could I at least do the kitchen/dining as one color and the living room another color?

-Please tell me I have options other than green

Different Options I've Read:

-Go with green is what we read the most (we're nervous we won't like it, or it'll feel dingy)

-Navy for the kitchen

-Stay neutral/beige (not my post. bonus content for anyone in the same boat: color theory stuff, every color looks different in every space, etc)

-Approach beige with caution (not my post)

All The Details, if you want them:

We rented a long time before we bought our previous house so we're tired of beige and warm neutrals. I don't know how to incorporate wall colors that won't feel "blah" for me because my instincts say we need warm colors here but we tend to like grays and cool tones. Navy is the most intriguing option we've seen, but a lot of those examples have some sort of gray in the countertops and we don't. I'd definitely want to keep navy secluded to the kitchen area because of how dark it would be, which bounces back to my question of do I HAVE to paint all 3 spaces the same color in order to flow?

These are the listing photos, none of this is my furniture. But unfortunately we are already fairly monochromatic... Our leather couches are dark brown and so is the coffee table, the end stands, etc. We haven't bought a dining table yet but would probably default to brown unless advised otherwise.

This is a pretty new house and we'll likely re-sell in several years so I'm not looking to change the cabinets, counter, or backsplash. I'd rather work with them and compromise on the wall color.

We honestly don't have much other decor or themes we have to "work around" aside from furniture. We're very flexible in that aspect.

We of course will start swatching when we move in but we'd like to get the painting process started ASAP so I'd like to narrow it down before we get there to be more efficient. I don't want to end up in the nightmare situation of 7 trips to the store for 12 colors to try, etc... I'll probably bring a cabinet door with me to the store but that paint wall is overwhelming.

Even though we like cool colors we are open to any suggestions that will go with our furniture, cabinets, and counters. I just know if I go with colors I "like" it's going to clash. And what I see now from the photos is just "brown on brown on brown on brown" which I don't like. Help!
