What does harmonious mean in colour terms?

In color terms, "harmonious" refers to a pleasing arrangement of colors that work well together, creating a sense of balance and unity. This often involves the use of colors that are adjacent on the color wheel, such as analogous colors, or colors that complement each other, like complementary pairs. Harmonious color combinations can evoke specific emotions and enhance the overall aesthetic of a design or artwork. Ultimately, harmonious colors contribute to a visually appealing and cohesive look.
