Zao's works, influenced by Paul Klee, are orientated to abstraction. He names them with the date in which he finishes them, and in them, masses of colours appear to materialise a creating world, like a Big Bang, where light structures the canvas. He worked formats in triptychs and diptychs. While his work was stylistically similar to the Abstract Expressionists whom he met while travelling in New York, he was influenced by Impressionism. Zao Wou-Ki stated that he had been influenced by the works of Matisse, Picasso and Cézanne.
