9The Hard-Edge Painting style was popular in the 1950s and 1960s. Although it was first identified with Californian artists, today the phrase is used to describe one of the most distinctive tendencies in abstract painting throughout the United States in the 1960s. The style combines the clear composition of geometric abstraction with the intense color and bold, unitary forms of Color Field Painting. Notable artists who adopted the style include Frederick Hammersley, Karl Benjamin, Lorser Feitelson and Frank Stella.
