There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

Where is the other window placed and what is its geographical direction?

If your ceiling to floor height is approx. 8- 9' , and there is sufficient light from the windows, we suggest 5 w for ambience light, 10 w for general light and 15w for task light. Living room should be a combination of yellow and natural light. if it will be used as work area for study , then white light should be included. Generally school projects are made on dining table so white light should be used along with yellow. Kitchen task light should be white. Passage and bedroom could be yellow. Ambient light is generally warm white and yellow. For watching TV, indirect and ambient light is advisable.

Go for some light color as the room needs to be bright cause there in no natural light source and provide sufficient light source so that your space will visually look bigger and brighter.
