What kind of art uses only 3 colors?

Art that uses only three colors is often referred to as "triadic" art, which employs a color scheme based on three evenly spaced colors on the color wheel. This approach can create a vibrant and dynamic visual impact while maintaining balance and harmony. Artists may use this technique to simplify their palettes and emphasize composition and form, often seen in various styles, including abstract and minimalist art. Examples include works by artists like Piet Mondrian and certain pieces in pop art.
