Fauvism was an early 20th century art movement known for bold, vibrant colors and loose brushwork. Henri Matisse was a leading Fauvist painter who rejected realistic color usage in favor of expressing emotion through color. His works like Luxe, Calm and Volupté (1904) showed this new approach through simplified forms and bright hues. Later paintings like Dance (1910) further flattened forms and used intense colors to depict movement in a simplified, rhythmic style that was radical for the time. Matisse's experimentation with color played a key role in developing Fauvism's distinctive style.
