Yes I agree. Please do not make the mistake of using color on the drapes. You have enough going on in your room with wall grid and fireplace. I would put the drapes on a quiet rod (no jazzy finials) almost at the top of the ceiling outside mount on the wall. It will make your room feel bigger and more architectural. Match (or in the color range) the drape color to the walls. Not a heavy fabric - something light in feel. You want one (may be custom depending on window length) pull down blackout shade in a cream or white at the top of the window inside mount for at night. If you want any pattern or color put it on pillows or one piece of furniture vs all the rest. I would be very careful to put a pattern rug in that room - very difficult to find the right one to pull it off with the wall grid.

You could use color curtains but you'll need to repeat the color in the room. Did you plan to add throw pillows or a rug? What about art?

I think accent colors look best/intentional when repeated least three times in large, med, and small areas.

If you have leftover paint and are able, I'd paint the white trim on the wall (not the crown moulding) to match the beige paint.

Please say more about what you cover window with, at night? do you already have a blackout-type there?

If I'm not mistaken, those are for hooks. Maybe these are right - they have other sizes and colors:
