Looks like you have a nice place! I think that before choosing an accent color, you should purchase a smaller accent piece (throw pillow, small piece of art) to see what colors you like with the paint, and then have the paint matched to that color. Here are a few options that I think would go well with your color:

I think a rust color would look great as an accent. Our dining room has a similar wall color and the ceiling is painted SW Earthen jug. I think it would look good in your room too. Consider painting the recessed ceiling with whatever accent color you choose.

Ok thank u guys. Do u think navy blue would look ok? Or red accent pieces?
