This document summarizes action painting, a style of abstract expressionism characterized by energetic and expressive application of paint. It was pioneered by artists like Jackson Pollock and Willem de Kooning in the 1940s. While some viewed action paintings as random splatters, the document analyzes works by Joan Mitchell, Jackson Pollock, Jean-Paul Riopelle, Helen Frankenthaler, and Willem de Kooning to show how they demonstrate control and composition despite their gestural styles. It addresses the criticism of whether such works can truly be considered art.
