Didn't you hear that grey color is a very fashionable trend now and everybody tries to find beautiful grey bedroom ideas? So, I think this color will suit you because grey looks amazing with every other color. Personally, I painted my kitchen in grey and this looks awesome!
Try gold colored curtains. If you want high contrast perhaps try a shade of purple.
There are so many colors that would look great. Pull a color from the furniture or accessories you have in the room, then it will look balanced and cohesive.
