You have all the reasons to redo the house, its very lifeless and looks worn out. I feel creating a separation will terminate the spaciousness of the room. Adding colours will surely help, Since you have a tan color sofa,I suggest grey, white or light blue color on one of the walls. Add some art works of the color you chose for the wall. This room needs some fillers like , books, throws, candle stands tall and lean. YES DON FORGET 1. Mount the tv on the wall make some space on the floor and Fix a large size mirror ( Wooden Frame if you can afford).

One of my favorite new contemporary pieces that can be found on the Dutchcrafters website is this great buffet. The black would really pop against that lovely red color! The buffet can be found here: http://www.dutchcrafters.com/Amish-Contemporary-Carson-Buffet/p/45833

Colour is fun but I don't feel yellow brown will be an inviting foil to the cream. Wood in that tone would be fine. How do you want to feel in your room? Fresh light airy? The. Go white. Cool edgy look - then add colour but be brave. Tomato red or Sea Blue or Coral.

I see this post it really old, but if you haven't already, with blue roof, you can go with white or white toned wall paints, or give it a Moroccan look by painting the walls mustard and doors and windows white. This color scheme is very lively.
