Post-impressionism is an art movement that emerged in the late 19th century as a reaction to the limitations of Impressionism. While Impressionist artists focused on capturing light and everyday scenes, post-impressionists sought to express deeper emotions and ideas through their work. They often used bold colors, distinct brush strokes, and abstract forms to convey their personal visions. Key figures of post-impressionism include Vincent van Gogh, Paul Cézanne, and Georges Seurat. Each artist had a unique style, with van Gogh known for his emotional intensity, Cézanne for his geometric approach to form, and Seurat for his pointillism technique. This movement laid the groundwork for modern art.
