The color palate in the room is another helpful tool to blend different living room ideas. If the colors blend, even if the décor dramatically contrasts in concept, you can get away from it. Color mediation is really a solution if you are going to have your sports fan décor within your wife's traditional living room area. You could tone on the bright colors of a Lakers helmet simply by using a vintage display case. You could also print pictures in white and black or sepia prints to intertwine the two themes. Consult your color wheel to choose an appropriate color scheme. Keep the colors in the same family unless your theme is rainbow. Sometimes contrast looks awesome. For instance a colorful, woven bohemian blanket would pop nicely against a modern, stark white couch.
