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).

Wow! red or maroon are very strong colours. Without knowing your tastes, your furniture, your flooring your walls or even your artwork, it is very hard to give you advice. Red - strong, vibrant, passionate, hot. Works with most wood colours except a cherry wood which has reds in it. Works with the non-colours - black, white, grey. Works with high saturation colours and clashing colours such as turquoise or hot pink. Maroon - muted, calming, moody, dark. Works with most wood colours except possibly black which would be dark on dark. Works with muted colours best of the same tone category: olive green, yellow ochre. Likes gold and silver. More elegant

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

Not sure if i would paint it white. Try an off white maybe, but i would keep the chair as is and try a mustard gold plain fabric for the upholstery and place a red cushion on the seat. We would help you with more colour ideas if there was a picture showing the rest of the interior where this chair is. red scatter
