“Klee channeled his mood through the process of using areas of color that he then outlined or added figures to embellish. Some of his paintings are simply color and shade studies, juxtaposing light and tone to produce a thing of lyrical beauty.

When his work was criticized as little more than the scribbles of a child, he claimed to be delighted.”
