Informalism is an art movement that emerged in the mid-20th century, characterized by a focus on spontaneous, non-representational forms. It emphasizes the process of creation over the final product, often using unconventional materials and techniques. Artists associated with this movement aim to express emotions and ideas through abstract forms rather than traditional subject matter. Key figures in Informalism include Jean-Paul Riopelle and Wols, who utilized gestural brushwork and dynamic compositions. This movement is often linked to Abstract Expressionism and reflects a broader shift in the art world towards more personal and subjective expressions, moving away from established artistic conventions.
