In the same way that polarized personalities can bring out the best in each other, so do colors that sit opposite each other on the color wheel.
These are called complementary colors, and they draw from warm and cool sides of the wheel, intensifying one another. The drama of these duos makes an exciting combination. Dining rooms, kitchens, playrooms, and party rooms are excellent candidates for complementary schemes.
Still not sure how to construct a complementary scheme? Let professional colorists do the work for you: look for fabrics, patterns, and wallpapers that already include opposite colors.
Remember too that you needn't use the brightest colors for a complementary scheme. For example, though red and green are complements, so are lighter shades of medium pink and sage, rose and hunter, pastel pink and apple green.
Consult a color wheel if you're unsure of a color's complement. You can get one at an art or paint store for reference.
