Generally, post-impressionism was not considered as a style in real sense because the postimpressionists did not form a group and they did not jointly hold any painting exhibition. Furthermore, they did not make any declaration. At first, they were fascinated by impressionism, but they broke away from impressionism at last and began their own way of art creation. Post-impressionism differs from impressionism in theory and practice. The postimpressionists paid more attention to subjects in daily life, exterior light and color of objects. They preferred to express their personal feelings and experiences. They also experimented with the natural use of color.
Post-impressionism made fully use of the formalist art for almost any subjects and contents. The impressionists stressed on displaying the materiality, stability and inner structure of objects in daily life. They focused on creating visual senses of weight, volume, solidity and grandness for simple and geometric effect. Post-impressionism is considered as the primogenitor of the Cubism and Abstractionism. Besides, post-impressionism leads directly to the birth of Structuralism. Thus, the postimpressionist paintings played a significant role on the development of modern art styles.
Representative postimpressionist painters include Paul Cezanne, Paul Gauguin and Vincent Van Gogh. They made great contribution to the development of post-impressionism. They put emphasis on representing the relationship between form and structure of natural landscapes as well as color arrangements. They paid little attention to the exact quality and shape of the objects, but they highlighted the senses of weight and stability as well as the overall relationship between the objects. Moreover, they were excellent in coloring and object shape building.
