The color palate of your room is another helpful tool to blend different living room ideas. Even if the décor dramatically contrasts in concept, you can get away using it if the colors blend. Color mediation can be a solution if you are going to have your sports fan décor inside your wife's traditional living area. 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 brightly colored, woven bohemian blanket would pop nicely against a modern, stark white couch.
