Although "Color Field" is associated with Clement Greenberg, Greenberg actually preferred to use the term "Post-Painterly Abstraction". In 1964, Clement Greenberg curated an influential exhibition that traveled the country called post-painterly abstraction. The exhibition expanded the definition of color field painting. Color Field painting clearly pointed toward a new direction in American painting, away from abstract expressionism. In 2007 curator Karen Wilkin curated an exhibition called "Color As Field:American Painting 1950–1975" that traveled to several museums throughout the United States. The exhibition showcased several artists representing two generations of Color Field painters.
