Color pictures in art refer to visual representations that utilize color as a primary element to convey meaning, emotion, or visual interest. The use of color in art has been influential in various movements and styles, such as Impressionism, where light and color were emphasized, and Fauvism, which embraced bold, non-naturalistic colors. Artists often use color theory to achieve specific effects, such as complementary colors to create contrast or warm/cold colors to evoke moods.
