Do you have photos you can share? I would pick one of the colors from the hard finishes. Is it open to other rooms? What other colors are in or near the space.

Well, #1, white vinyl divided pane windows do not go with that interior. I'd swap those out or figure out some way to minimize their intrusion because they're going to stick out even more if you change the color of the walls to something other than white. You have a lot of really good options with that living room design. At minimum, I'd pick a slightly different shade for the wall next to the stair well and the stair well itself, so it appears as a different dimension. With the 'beamed' ceiling, there should be some subtle transition from the 'wall' to 'ceiling' area color wise. Otherwise the beams look like they're just floating or tacked on (which they probably are, but as long as they're there, make them look like they're actually part of the ceiling rather than something stuck on the wall) After a second look, another option with that nice high ceiling is to do the walls a slightly darker shade than the ceiling, then replace those wall sconces with something that directs light at the ceiling. This will give the whole room a nice 'glow from above' all with indirect light. and make the ceiling feel even higher.

Oops edited to say: the colors are in the same order from left to right as they are top to bottom. Don’t mind the letters I marked over the colors, they are for my own memory:)

Oh good! Painting the ceiling will be transforming...you'll see. About the niche and fireplace art ....Kelly's concepts are stunning. Wow. That's a nice brown next to the fireplace...it has a little gray iin it. I like the Blue Abstract against the browns...get that Blue one. Here's a screenshot from art.com if you can read the titles. I searched blue abstract botanicals and stuff blue coral couldn't find it
