What color curtains go well with my smoky blue walls in my living room bay window?

I just painted my living room blue. It is called evening eclipse from the valspar collection at lowes. I am wanting to put curtians in my bay window and im not sure what color would match the walls. I am open to many colors just not wanting to use white cause i already have crown molding that is white. My couch and chairs are a dark chocolate and my hardwood floors are stained a medium brown. Does anyone have any suggestions on some colors to use. My style im trying to go for is contemporary. All opinions are greatly appreciated!! Thank yo so mch!!
