The color palate from the room is another helpful tool to blend different living room ideas. Even if the décor dramatically contrasts in concept, you can get away by using it if the colors blend. If you are determined to have your sports fan décor in your wife's traditional living room, color mediation is a solution. By using a vintage display case, you could tone down the bright colors of a Lakers helmet. You could also print pictures in black and white 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.
