Color rhythm design refers to the arrangement and organization of colors in a visual composition to create a sense of rhythm and harmony. This concept is often applied in graphic design, interior design, and art. The composition of a picture using color rhythm involves selecting appropriate colors, understanding color theory, and arranging them in a way that evokes a desired emotional response or follows a specific design principle. Color theory includes color harmony, color contrast, and color psychology, which are essential for creating effective visual compositions.
