I would paint that wall the same as the rest of the room to camouflage the uneven angles. Add some color with Artwork. Let that Art make the focal point not the accent wall color. Depending on the other furnishing in the room, the walls could have more color than a neutral white. I would choose the Art first and use it and the furniture to determine wall color. Also consider the natural light in the room. Strong sunlight can take deeper shades.

I totally agree! But since we don’t want to repaint the rest of the room (and don’t have matching wall color) I think it’s going to have to be a different color. A warmer green? Tan? All I know is that I want this blue/gray color gone!

I like the entry paint color. I suggest you change the rug…to a silver one with highlights and size to the entire floor space. Add silver accent piece into the niches. No accent wall…use art instead. What I am not loving is the dining room paint. Assuming it is getting West light, it too brassy for the room and too whimsy for the adjoining entry color. Saturated and meant for West light, Province Blue would be stunning with the white wainscoting so.

Yeah, I agree! There's enough going on visually with the multiple rooflines and white trim outlining everything. Sometimes less is more. Im guessing the intention was to match the color of the stonework below but I dont think its necessary - the stone as part of the foundation (essentially) can just stand on its own as a handsome natural element. Maybe youd want to use that same stone in landscaping ..... or not - LOL
