What is Hard Edge Art?
Hard Edge art is a style of abstract painting that became popular in the 1960s. It features areas of color separated by crisp, sharp edges that are painted with geometric precision. The term hard-edge painting was coined by art critic Jules Langsner to describe this approach, which contrasts with the softer, more fluid forms of other abstract styles.
