Curtain Color Advice for Frontroom?

I am looking to put curtains in my frontroom and am not sure what color to go with. The walls are a light green, the floor is light wood, and the wood trim is dark. I have a tan area rug, the couch is maroon with a design of greens and yellows, and the recliner is green. What color of curtains do I use? Dark or light?
