The Berlin-based artist Katharina Grosse is known for the vibrant palette and exuberant gestures of her large-scale canvases and raucous installations that merge painting, sculpture, and architecture. Grosse is a Professor at the Kunstakademie Düsseldorf in Germany.

Scale is the psychological aspect of the work, whereas size refers to its measurable appearance.
