B.T.
We did a fire truck border around the middle of our son's room since our ceilings are slanted. He likes it better because it more at eye level for him. Then you can either paint the top half one color and the bottom half another or paint the whole thing the same color. We picked yellow (lemon ice) to bring out the color that was of the smallest amount on the border. It not only brightened up the room but it also brought attention to the light bars, ect. associated with heroes. Plus it kept his room from being so dark with all the red, blue, and black in the fire trucks and police cars. But light blue would have worked with it also. Hope this helps.
