What Red Lines Can Do (Harrison 24), 1970

Helen Frankenthaler (1928–2011) was a pivotal figure in 20th-century American art, best known for her role in the development of Abstract Expressionism and the Color Field movement. Her groundbreaking soak-stain technique, in which she poured thinned paint directly onto unprimed canvas, allowed colors to flow and merge in a way that created expansive, luminous fields of color.
