When two colors are mixed together, the result is a new color that is created by the mixture of the two colors. This new color is often called a “complementary color.” Complementary colors are pairs of colors that are opposite each other on the color wheel. For example, red and green are complementary colors because they are opposite each other on the color wheel. When these two colors are mixed together, they create a brownish-gray color.
