What cool color can I use to balance out all the warm yellows and golds in my bedroom?

I'm trying to stage my bedroom without spending a fortune. My walls were a fairly pale balanced (neither too warm nor too cool yellow) and I bought a pretty intense golden sheet set for my bed and gold curtains online... the curtains were supposed to be more like ivory with a little gold in the print, but what I got was a deep old gold and they darken the room a bit more than I'd like. I'm on a time crunch and can't send them back now... they're up and they look fine. The floor is oak hardwood, more golden color, lol. Also between the curtains and the sheets and my deep gold lampshade I've got a lot of feminine pattern going on in the room.

So, I need to buy a bedspread today and it needs to be fairly solid in color without a lot of pattern. I was thinking of getting something in ivory that has a sheen to it because the room looks pretty formal so a plain cotton one wouldn't look right. But I'd rather add another cool color to the room, like a pale aqua or something... trouble is I can't envision it. I need to go light or pale because the curtains, floor and oak trim in the room are really darkening it.
