Complementary adjacent colors

Quick answer：

Complementary adjacent colors refer to a color scheme in which two colors that are complementary to each other are placed next to each other on the color wheel. This creates a dynamic and visually appealing contrast. For example, blue and orange are complementary colors, and placing them next to each other can create a striking effect. In design and art, this technique can be used to draw attention to certain elements or to create a sense of harmony.
