It's hard to say without knowing your style and what's going on in the rest of the room. I would say a bright color. Or even a black to tie in your railing.

I agree with Kimberly, hard to know without seeing your style. But I would suggest a dark paint that still has some colour and soul. How about a "hudson bay" CC-810 or a "radicchio" CC-32 as possibilities.

Cheers!
