Post-Impressionism developed in the 1880s-1900s as an artistic movement that broke from the limitations of Impressionism. While still using vivid colors and brushstrokes, Post-Impressionist artists such as Paul Cezanne, Vincent van Gogh, Paul Gauguin, and George Seurat were more inclined to emphasize form and use unnatural color to convey emotion and personal expression over natural scenery. Each artist developed their own unique styles, such as Cezanne's reduction of objects to basic geometric shapes or van Gogh's swirling brushstrokes expressing his feelings, though they did not entirely agree on a cohesive movement.
