Which colour theory involves using colours opposite each other on the colour wheel for high contrast?

Explanation

Complementary colors sit opposite each other on the color wheel. Red and green, blue and orange create strong contrast. This pairing makes colors look brighter.

Analogous colors sit next to each other. Monochromatic uses one color in different shades. Complementary specifically uses opposites for maximum contrast.

Artists use complementary colors for bold, eye-catching designs. The contrast creates visual energy. This technique appears in art and graphic design.
