“Error on green” is an artwork by Paul Klee, created in the year 1939. Klee’s work is associated with the Surrealism movement, and the piece in question falls within the genre of portrait. This artwork is housed at the Beyeler Foundation located in Riehen, Switzerland.
The artwork manifests a dreamlike scene consistent with Surrealism’s predilection for the subconscious and the bizarre. Two figures, both cloaked in shades of darkness, occupy the composition. The figure on the left appears to have bird-like features, suggesting an anthropomorphic entity, while the figure on the right, clad in a tuxedo, retains a more human likeness. Both figures have pronounced facial expressions that seem to be engaged in an enigmatic interaction. The contrast between the fauna-flavored visage and the formal human attire imparts an air of absurdity and dissonance, inviting viewers to ponder the dreamlike juxtapositions that Klee was known for. The use of dark hues imbues the artwork with a certain weight and profundity, emphasizing the depth of the metaphysical landscape that Klee has crafted.
