The term "Post-Impressionists" refers to a group of artists in the late 19th century who built upon the ideas of the earlier Impressionist movement. While Impressionists focused on capturing light and everyday scenes, Post-Impressionists sought to express deeper emotions and ideas through their work. They experimented with color, form, and perspective, often using bold colors and distinct brushstrokes. Key figures in the Post-Impressionist movement include Vincent van Gogh, Paul Cézanne, and Georges Seurat. Each artist had a unique style, contributing to the diversity of the movement. Their innovative approaches laid the groundwork for modern art, influencing future movements such as Fauvism and Cubism.
