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 .

Either, you can paint all the walls with light grey or white colour. Or, highlight one wall with light grey colour and rest of the walls can be white.

use can go cream colour insted of blue and white go with eggshell like colour can you can apply readymade highlighter and golden moulding on corner

When the sunlight doesn't touch the wall surface, white tends to look grey and dull. Window Walls tend to have this problem especially if none of the adjacent walls have windows. One trick to liven up the window wall is to paint it in a rich, warm yellow tone. As shown in the attached picture. But don't paint any other wall in the room in this colour, as it will be overwhelming.
