Need help deciding on a color for an accent wall.?

My living room flows right into the dining room, so the paint colors are right next to eachother and when you walk into the house and turn, you will see the creamy white walls of the living room and then the sage colored dining room. I want to paint the fireplace wall that also has 2 small windows on each side an accent color. I don't want anything too dramatic, but something that goes well with the colors I mentioned. I also have all dark wood furniture, a red sofa and all the moldings and window frames are wood. Any suggestions would be appreciated.
