What Color Does Red and Green Make?

Mixing red and green together makes the color brown. The three primary colors are red, blue and yellow. Green is formed by mixing blue and yellow, and it is a secondary color.

The other two secondary colors are purple, formed by mixing red and blue, and orange, formed by mixing red and yellow. The tertiary colors are formed by mixing a primary color with an adjacent secondary color. The tertiary colors are blue-green, yellow-green, yellow-orange, red-orange, red-violet and blue-violet. Red and green are complementary colors, as are blue and orange and yellow and purple. Mixing two complementary colors results in brown.
