I think you should stay with a simple pattern for draperies. Possibly a pattern incorporating the white trim and warm yellow walls. This would be soft and understated and something that you wouldn't get tired of easily. Other colors could be introduced with accessories.

Thank you Shalaka ! I do love it the way it is but since the windowstart are ceiling to floor and facing West, in summers it becomes a furnace. Hence the need for double curtains. So wanted to get something that when needed if I tie the front cream ones from the back when they show, it looks nice. While my husband liked orange, I was leaning towards, gold. So we decided to put it for vote. Thank you for your input :-)

if u have 6" space beside tv end and beside sofa... then u can shift the sofa towards left after the window ends and shift tv unit along with the low height storage, I thin tv uni t is movable, and can be shifted.. if possible for u the u send photo which has view of entire space.. take photo from far... i need to see what space is there beside tv unit other end and sofa other end... after that u can use full height curtains .. to fulfill ur wish

Sheer Blinds are a good option. Put some plants outside if possible that will lend greenery to the inside too. Above is an image from one of my projects.
