Harmonious color pairing effects

Quick answer：

Harmonious color pairing, also known as complementary color pairing, refers to the combination of colors that are adjacent on the color wheel. This creates a visually pleasing and balanced effect. The concept is widely used in design, fashion, and art to evoke emotions and create a sense of unity. Colors that are next to each other on the color wheel, such as red and orange, or blue and purple, often complement each other well.
