Analogous colors and complementary colors

Quick answer：

Analogous colors are hues that are next to each other on the color wheel, such as red and orange or blue and green. Complementary colors are pairs of hues that are opposite each other on the color wheel, like red and green, or blue and orange. They create a vibrant contrast when placed next to each other. In design and art, understanding these color relationships is essential for creating balanced and aesthetically pleasing compositions.
