Theater color

Black or Charcoal gray is optimal. Burgandy is fine. If you use medium to dark colors they will all work ok. If you use light contrast trim or carpet with contrast design they will all "pop" out and highlight when the picture gets bright. Avoid chrome, brass and poster frames with glass for the same reasons. Real movie theaters are dark and plain on the inside.

i'm certain you can use dark burgundy without any problems. as long as the color is sufficiently dark enough not to reflect much light, you should be fine. make sure to post pics when you're done.

Never herd green was best but anything dark and flat should be fine. dark burgandy is the most popular think or real theorthers blue I have also seen. never seen green might be nice though.
