Color wheel 101 teaches us that the colors directly opposite of each other on the color wheel are complementary. I didn't spell that wrong - they don't compliment each other, they complement or complete each other. In color talk, that means they make each other look their best, they bring out the best in each other - like a good marriage. If you want to bring out a particular element in your home - a specific wood tone, the sofa, grandma's quilt, or a painting for example - find its dominant color and complement it - find the opposite color. The photo above is a perfect example - the gold/yellow and peach tones of the roses pop against the purple tones of the lilacs. Yellow and Purple are opposites on the color wheel.
