Abstract expressionism
Guston rose to prominence as a first-generation abstract expressionist in the 1950s, though he preferred the moniker New York School. As seen in his work Zone, 1953–1954, his paintings mainly composed of blocks and masses of expressive strokes and colour markings floating inside the image plane. These paintings are reminiscent of Piet Mondrian’s “plus and minus” compositions or Claude Monet’s late Nymphea canvases, with markings gathered toward the centre of the piece. Guston’s palette was restricted, with black and white, greys, blues, and reds dominating. Despite Guston’s late attempts to widen his palette and return abstraction to his work, as demonstrated by some of his nameless work from 1980 that contains more blues and yellows, it was a palette that would stay present in his later work.
