What is Complementary Colors?
Complementary colors are directly opposite each other on the color wheel and when combined or mixed, they cancel each other out (lose hue) due to producing a grayscale color like white or black and blue or yellow.
Complementary colors are pairs of colors on opposite sides of the color wheel. As an artist, knowing which colors complement each other can help you make good color decisions. For example, complements can make each other appear brighter, they can be mixed to make an effective neutral color, or they can be mixed together for a shade. Complementary colors are always found opposite each other on a color wheel and have the quality that they appear brighter when placed next to each other.
