Aww, you have great taste.
Maybe that will warm the room up itself, the "quilting" effect if you know what I mean, it's a sewing term...
Maybe find something Gold and something Silver from around you house, a decent size and see what each look like in the room & then decide what you think looks best - just an idea?
I am thinking Silver would look more suited in the room.
Can't wait to see final pictures! Good Luck with what you decide, I am sure it will look great
