Newman is generally classified as an abstract expressionist on account of his working in New York City in the 1950s, associating with other artists of the group and developing an abstract style which owed little or nothing to European art. However, his rejection of the expressive brushwork employed by other abstract expressionists such as Clyfford Still and Mark Rothko, and his use of hard-edged areas of flat color, can be seen as a precursor to post painterly abstraction and the minimalist works of artists such as Frank Stella.
