What is Colour Field Painting?
Colour Field Painting is an abstract style characterized by large areas of a single color or simple, solid colors. The term was first used in the 1950s to describe the work of three American Abstract Expressionist painters—Barnett Newman, Mark Rothko, and Clyfford Still. Their work emphasized the emotional power of color and the creation of vast, meditative spaces through expansive color fields.
