The Blue Four was formed in 1924 by Klee, Kandinsky, Feininger and Jawlensky when they were all four teaching at the Bauhaus, Weimar.
The spirit of 1924 is still alive and the influence of The Bleu Four can be seen in much of the modern art of today. Kandinsky wrote in 1913: "A work of art consists of two elements, the inner and the outer. The inner is the emotion in the soul of the artist. This emotion has the capacity ot evoke a similar sensation in the observer... The inner element, i.e. the emotion, must exist otherwise the work of art is a sham. The inner element determines the form of the work of art."
