Тетрадные цвета

Tetradic (also called double-complementary) schemes are the richest of all color harmonies because they use four colors from across the wheel. For instance, blue and orange paired with red and green. The key to making tetradic schemes work is to let one color dominate and use the others as accents, ensuring the palette does not feel chaotic. Tetradic schemes provide plenty of variety and are popular in complex designs like magazines, dashboards, and data visualizations where multiple distinct categories need color coding.
