Evening; Red Tree is an oil-on-canvas painting by the Dutch artist Piet Mondrian from 1908. It is commonly referred to as The Red Tree. The painting is an Expressionist representation of an apple tree with branches that spread wide across the canvas. The Red Tree is the first painting in Mondrian’s Trees series, which defined an important period of evolution in Mondrian’s work as he transitioned to Neoplasticism. Mondrian used The Red Tree to express his views of nature and reality as a complex equilibrium between harsh motion and quiet stillness. The painting displays non-naturalistic colours and simplified tones of red and blue.
