The Swiss-German painter's work blended abstraction, color theory, and symbolism. Influenced by Expressionism, Cubism, and Surrealism, he developed a highly personal style, often using playful shapes, vibrant colors, and intricate patterns. As a Bauhaus teacher, he explored the relationship between color and form, inspiring generations of artists. His work, initially misunderstood, later became widely celebrated for its depth and imagination. Klee believed art should reveal hidden realities, stating, “Art does not reproduce the visible; it makes visible.”
