I personally think a black and white room is sharp and provides a unique look. I understand if you want some color on the walls so I attached some other spaces with paint colors you may like. The cool blue is great with black and white as is a cement colored gray.

Green is the best color. If you don't want to go with that, go to a paint website and go through colors and see what you like.

I post boutique hotel awards because I'm totally inspired with their color combination and furniture. Especially the way in which they decorate their bedrooms. All are awesome, if you have any site like boutique hotel awards please share with me. Thanks in advance @ SandyC.

Your setting is good but could be better.the centre table is a misfit.you can use 2 level rectangular table either white poly paint one level and the other level glass or black paint or poly paint.keep the length of the table after leaving approx 16 to 18"on either side.the width can be20-22 " and ht 16".the cushions can be change to black and white design,with a dash of red.a nice rug with grey,black and white geometric design will enhance the effect.brown does not go well with white.i hope this should solve your problem.once you make this change.you eye will pick up the other flaws.
