I'm in a rental and hated the powder blue color on the accent wall. I changed the left side to the same white as the rest of the area, and the right side to "sky space" by Valspar. Now the couch and my mirror collection pop nicely.
(as you can see I tested many paint chips in reds and mauves, but the blue/green won over)
