Farbtafel, 1930 by Paul Klee
Paul Klee (18 December 1879 – 29 June 1940) was born in Münchenbuchsee, Switzerland, and is considered both a German and a Swiss painter. His highly individual style was influenced by movements in art that included expressionism, cubism, and surrealism. He was also a student of orientalism. Klee was a natural draftsman who experimented with and eventually mastered colour theory, and wrote extensively about it.
