Can you share some photos of the room?

If you are talking wood blinds, I recommend you stick with a color that matches the trim. This way you are not locked into a color you may tire of eventually. The exception might be a billiards room or library where a dark color scheme sets the mood.

Check out the new shades called Vision Shades. You can see them at http://www.solarscreenshade.com

I would stay in the earth tones and bring in color with accessories.
