채도 refers to the intensity or purity of a color. It indicates how much gray is mixed with a color, affecting its vibrancy. A high 채도 means the color is bright and vivid, while a low 채도 results in a more muted or dull appearance. In art and design, understanding 채도 is essential for creating visually appealing compositions. Artists often manipulate 채도 to evoke emotions or set the mood of a piece. By adjusting the 채도 of colors, they can achieve balance and harmony in their work.
