Green loveseat, black furniture and dark red for the walls and matching pillows, and the curtains?

Question

What color should the curtains be with such combination?

Answer 1

green?

that's kind of a weird color palette

Answer 2

medium taupe since i can't see the shades you're talking about

Answer 3

I guess green or black, but If you can I would paint the walls to a beige or tan color. Red and green, although they are complimentary colors remind people of christmas when placed together.
