Try a light grey. I wouldn't go beige with the yellow. Dark wood looks great with grey walls. Yellows and brown also work well with grey. So pick a light grey and good luck.

Is there a reason you have those colors on the walls? Without pics we are in the dark. What exactly is your style ?

Hello there, It looks like the wood primer has got the wrong shade. It should have been teak/pine. He has applied walnut primer. The only solution is to sand off the entire primer and reapply an appropriate coating. But it is going take some skills as well. Go for a clear coat instead after sanding. It will bring out the grains and textures very well. Regards, Aurum Ideas and Spaces Bhubaneswar

I feel partitions are not needed. You already have too much for the space. Adding a partition will shrink the space further. The simplistic solution, you do not wish to discard any furniture would be to paint all the walls in lighter pastles. And use some wall painting frames to highlight certain walls.
