Double-split complementary colors are the four colors on either side of a pair of complementary colors on the color wheel. Complementary colors are exactly opposite each other on the color wheel.
Double-split complementary color schemes are commonly used in the fashion industry. This complex scheme provides a lot of contrast in color while still blending harmoniously. An example of a double-split complementary scheme is red, orange, green and blue. This color scheme comes from the complementary pair red-orange and green-blue, which are color wheel opposites. Orange and red are on either side of red-orange, and green and blue are on either side of green-blue. A double-split complementary color scheme is a tetradic scheme because it includes four colors.
