I need help deciding on a bedroom paint color.

I bought this bedspread. I don't have all the matching pillows... I just have the lighter brown comforter, two light brown pillows, and the chocolate coverlet. I am going crazy trying to figure out what paint color to use. I'd like to go for a zen look - very relaxing and peaceful. I've tried tons of paint samples on my walls. Any suggestions? We have beige carpet and white trim. Thanks for your help!
