Color field painting is a style of abstract painting that emerged in New York City during the 1940s and 1950s. It was inspired by European modernism and closely related to abstract expressionism, while many of its notable early proponents were among the pioneering abstract expressionists. Color field is characterized primarily by large fields of flat, solid color spread across or stained into the canvas creating areas of unbroken surface and a flat picture plane. The movement places less emphasis on gesture, brushstrokes and action in favor of an overall consistency of form and process. In color field painting "color is freed from objective context and becomes the subject in itself." During the late 1950s and 1960s, color field painters emerged in parts of the United Kingdom, Canada, Australia, and the United States, particularly New York, Washington, D.C., and elsewhere, using formats of stripes, targets, simple geometric patterns and references to landscape imagery and to nature. Historical roots The focus of attention in the world of contemporary art began to shift from Paris to New York after World War II and the development of American abstract expressionism. During the late 1940s and early 1950s Clement Greenberg was the first art critic to suggest and identify a dichotomy between differing tendencies within the abstract expressionist canon. Taking issue with Harold Rosenberg (another important champion of abstract expressionism), who wrote of the virtues of action painting in his article "American Action Painters" published in the December 1952 issue of ARTnews, Greenberg observed another tendency toward all-over color or color field in the works of several of the so-called "first generation" abstract expressionists. Mark Rothko was one of the painters that Greenberg referred to as a color field painter exemplified by Magenta, Black, Green on Orange, although Rothko himself refused to adhere to any label. For Rothko, color was "merely an instrument". In a sense, his best known works – the "multiforms" and his other signature paintings – are, in essence, the same expression, albeit one of purer (or less concrete or definable, depending on the interpretation) means, which is that of the same "basic human emotions", as his earlier surrealistic mythological paintings. What is common among these stylistic innovations is a concern for "tragedy, ecstasy and doom". By 1958, whatever spiritual expression Rothko meant to portray on canvas, it was growing increasingly darker. His bright reds, yellows and oranges of the early 1950s
