I would suggest a dark color it would really bring out the texture of the curtains.
I disagree. The dark color of the curtains will blend right into the floor of a dark colored carpet.
With that in mind, it will be up to you to decide what temperature and mood you want to set with the cutains. Are they formal or traditional? If so, consider gold shades. Sandy, muted gold looks fantastic with Aubergine. Do you want to create a more modern feel or a cooler temperature? Pewter, silver and medium gray work well with Aubergine. Finally, You'll want to consider what furnishings you already have or what you'll want to use to determine the direction of the carpet color.
Green carpet goes with green curtains :P
