Try a mid-century modern rug like Hemphill's Rex Ray Area Rug Collection or Jaipur Traverse Caracas. I looked up 'mid-century modern rug' and chanced upon these on Houzz. I like the muted colours which would soften the cream on brown. The mid-century motifs would highlight the mid-century chair. Good luck!

I have a similar family room, with big windows and a sliding door and we have block out Roman blinds on them. They sit at the top of the windows most of the time as we don't have any privacy issues with being looked in at by the neighbours. We really only put them down at night in the winter. Ours have a creamy coloured background with taupy wavy lines on them. Very neutral. I never could have imagined that's what I wanted til I saw the fabric. Good luck I'll see if I can find a photo to post.

There are so many shades of taupe it is impossible to say without seeing some photos of your home. I would suggest that you start looking at some light teals and pale aquas, but it really depends on what else is in your home. Best of luck, Dr Retro of Dr Retro House Calls

As said by big reader...leave white or paint the same colour, without the brushed finish, on the other walls. You can not bring another colour in. There is enough colour already with the orange wood and the bed cover. Also, the curtains look too small to pull right across your window correctly. They should be waved not flat when closed.
