I have a color like this on the walls of my game room, with espresso colored leather sofa and chair, and blue/teal/lime accents. I used sheers the same color as the background color on your sofa, and the room looks great. However, you could go with black, too, depending on the carpet or flooring.

Instead of the solid grey, you can go for sketches in grey with flashes of mustard/ yellow. Or, look up these links for wallpaper ideas https://goo.gl/images/OrCtY1 https://goo.gl/images/0ZpAmU

Hi, I would suggest changing the furniture fabric first and formost, go for a solid colour say white, offwhite, grey or even brown, and use colourful cushions which you may keep changing. A light yellow more like a dull yellow with wall accessories will look great on the walls. . For the flooring , please use wooden laminates and repolish the ceiling (as i see is a lovely wooden ceiling ) to a similar shade. Change the curtains to a breezy white curtains. Avoid curtains on the door. Reduce the clutter and you have a wow living room . For more ideas you may use our edecor services , just mail us at snsofdesign@gmail.com with the above reference .
