Curtain Color Ideas?

I have a mixture of steel blue and sky blue walls. I also have gun stock hardwood floors. We're buying new furniture so the furniture doesn't matter, but I think I want navy blue or gray furniture maybe even white. I have no idea what color curtains to buy without putting too much blue in the room and I don't want solid white. Can anyone help? I kind of like the idea of peach pie, but don't want it to look like a circus.
