Which artistic features of Post-Impressionism appeared in Piet Mondrian’s work?

Piet Mondrian’s early work was significantly influenced by Post-Impressionism, particularly through the movement's emphasis on bold, nonliteral color and expressive technique.

The following features of Post-Impressionism appeared in Mondrian’s early artistic development:

• Bold, Pure Color: Influenced by the work of Vincent van Gogh, Mondrian began utilizing pure, brilliant colors in nonliteral ways. This is evident in his 1907 sketch Red Cloud, which reflects the daring color usage characteristic of Post-Impressionist painters.12
• Linear Movement: By 1908, Mondrian’s work began to incorporate a distinct linear movement, a stylistic evolution reminiscent of the work of Edvard Munch.1
• Technique and Palette: His engagement with the Dutch Luminist movement—an offshoot of French Neo-Impressionism—led him to experiment with rendering light through short strokes of primary colors, as seen in Windmill in Sunlight (1908). This focus on primary hues eventually became a foundational element of his later Neoplasticism.31

While these Post-Impressionist influences were vital to his early career, Mondrian eventually moved toward complete abstraction, rejecting naturalistic representation in favor of the geometric harmony found in his mature work.314
