Hard-edge painting is abstract painting built from sharply bounded areas of flat, unmodulated color. The label was coined by the Los Angeles critic Jules Langsner in 1959 for the exhibition Four Abstract Classicists, which gathered Lorser Feitelson, Karl Benjamin, John McLaughlin, and Frederick Hammersley - West Coast painters whose clean-cut shapes answered the drips and blur of Abstract Expressionism with cool clarity. In the early 1960s the term spread to New York, where Frank Stella's black paintings and shaped canvases, Ellsworth Kelly's flat color slabs, and Kenneth Noland's targets pushed impersonal precision to monumental scale. Grouped by the critic Clement Greenberg under post-painterly abstraction, hard-edge work treats the border between colors as the event itself: each edge is abrupt, each field is even, and the artist's hand disappears into the surface.

Defining characteristics
Abrupt, razor-sharp boundaries between color areas - no blending or feathering
Flat, unmodulated color with no visible brushwork
Geometric or simplified shapes: stripes, targets, irregular polygons
Impersonal, cool surfaces that suppress the artist's hand
Color relationships themselves treated as the subject, in place of figures or illusion
