From the 1880s several artists began to develop different precepts for the use of colour, pattern, form, and line, derived from the Impressionist example: Vincent van Gogh, Paul Gauguin, Georges Seurat, and Henri de Toulouse-Lautrec.
These artists were slightly younger than the Impressionists, and their work is known as post-Impressionism. Some of the original Impressionist artists also ventured into this new territory; Camille Pissarro briefly painted in a pointillist manner, and even Monet abandoned strict plein air painting.
Paul Cezanne, who participated in the first and third Impressionist exhibitions, developed a highly individual vision emphasising pictorial structure, and he is more often called a post-Impressionist.
Although these cases illustrate the difficulty of assigning labels, the work of the original Impressionist painters may, by definition, be categorised as Impressionism.
