Green Stripe (La Raie Verte) by Henri Matisse, painted in 1905, depicts Matisse's wife Amélie. It was created during the development of Fauvism, a brief early 20th century art movement known for its use of vivid, unblended colors. Fauvist painters like Matisse applied color expressively to evoke emotion rather than realism, with simplified forms and exaggerated perspectives, emphasizing spontaneity over detail.
