Two colours on opposite sides of the color wheel, which when placed next to each other make both appear brighter. The complementary color of a primary color
(red, blue, and yellow) is the colour you get by mixing the other two (red + blue = purple; blue + yellow = green; red + yellow = orange). So the complementary color for red is green, for blue it's orange, and for yellow it's purple.
