Just leave it like it is, since you want to keep the dark wood. Put a few accessories in the dining room??(looks like that is what this room is) that are the same wood color. I would paint the tubing on those chairs, the brown color too, rather than adding black into the mix. It will make it all blend together. If you have room, for a small occasional table against the wall in the walnut color, or a buffet in walnut, that would be nice too. I love the color of your walls. So nice to see someone post that actually has color in their homes, since so many today are boring.

Hi! I see what you mean but if you added more photos we could better help

Paint the walls the same tone as the abutting walls. Same strip, go up or down on the colors and choose one you like.

The biggest problem is the disparate flooring. One a lovely hardwood and the other an LVP which belongs in a beach cottage. A rug might help a bit.
