The color palate of your 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 by using it. Color mediation is actually a solution if you are going to have your sports fan décor within your wife's traditional family area. You could tone over the bright colors of an Lakers helmet by using a vintage display case. 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.
