I would advice you to go for all white and then have coloured art and accessories on the wall that you wished to have as accent wall. This way you won't be struck with one colour till your next repainting job. You will also have the liberty to change the colour pallet depending on your mood and season with just changing a few things like paintings ,cushion covers etc. involving very little cost and efforts.

Pista green color looks good. I was actually looking whether we can make something to contrast the blue glass windows.

I wish you all the best for your renovation. One of the most positive thing about the house is space looks convenient. To start of with the designing, 1. first let us start with a creating a focal point, now that the sofa Color is Blue, let us try creating a palette (photo attached) starting with blue, so we can paint white Color on the walls. 2. let us put on two mirrors on both sides of adjacent walls of the curtain which makes it look spacious and reflects light. It gives a cool effect. Even when the curtains are covered. 3. U many use a rug to match the Color of sofa and white walls. Make sure the rug is either beige or a combination of blue, white and grey hues. So that it complements everything well. 4. U may paint the wall behind the TV grey or give it a wooden panelling effect with wallpaper or tiles. That makes a focal point. 5. Increase the height of TV stand with Aluminium or Stainless steel rods, u will find them in the market and paint it white. (Photo attached)
