Complementary colors

Two colors opposite each other on the color wheel, like blue and orange. They make each other look more vivid.

Also called complementary color, complements, complementary

Complementary colors sit opposite each other on the wheel: blue and orange, red and green, purple and yellow. Side by side, each makes the other look brighter.

That punch is great for calls to action, like an orange #FF9B23 button on a blue #2387FF page, but use one as the main color and the other as an accent.
