Not with that sofa IMO.

I am afraid it would be too dark.

No. Too many accent walls will look choppy.

No,it won't add depth or sophistication. Why not wait on paint until your new furniture arrives. PITA I know, but you will get the best results.

Well this is how at all turned out.

Now I have a wall in the living room fifteen feet long. I’ve got the cabinet which takes up 6’ of the fifteen and I moved the tv there and mounted the mirror above it however the wall still looks empty to me any suggestions?
Second picture is of the fireplace opposite wall.

This is the wall.

Thank you

I did remove the accent color. Thanks for the suggestions. It was just a gallon of paint and sitting with my ideal and acknowledging a lesson learned. Thank you all
