Closest match to wall. Light beige was my vote

In the photo the walls look yellow and the carpet very taupe ... hard to say what color drape without seeing what else is in the room.

I agree no way to tell with the 2 tones of the walls and rug which BTW do not work well together . Iwould show th whole space and say if you are willing to either paint or get a new rug.

And another one leaves the building
