Cloisonnism is a 19th-century artistic movement, primarily associated with painting, characterized by the use of bright colors and bold outlines. Inspired by Japanese art, it is distinguished by the use of "cloison" (distinct lines) to delineate areas of color. Artist Émile Bernard is often cited as one of the pioneers of this style, which aims to create ornate and stylized compositions. Although relatively short-lived, Cloisonnism influenced later movements such as Synthétism and Art Nouveau, marking an artistic transition at the end of the 19th century.
