Andy Warhol was another artist whose visual representations became part of the Pop Art movement. While he engaged in numerously different forms of art, some of his fine art that he popularized throughout the 60's also conformed to several principles of Modernism as defined by Greenberg. Works such as Marilyn Diptych, which was initially exhibited in 1962 and was a work of silkscreen, certainly present an optical setting in which the imagery is confined to a flat, two dimensions, in much the same way that Lichtenstein's work did. The repetitions of the image of Marilyn Monroe's face are also simple and are contrasted against really subdued colors, which is another trait of Modernist art according to Greenberg.

As an abstract artist, Jackson Pollock produced a large amount of visual artistry that adhered to conventions of Modernism. Abstract art is modern in the sense that it relies on the optical as the sole means of measuring or regarding a work of art. Furthermore, the subject depicted in most of Pollock's work almost borders on being regarded as an object, and not necessarily a painting -- which is congruent with Greenberg's theory that Modern art is simplified and is decidedly pure in terms of its self-definition as being indicative of a particular medium.

Gerhard Richter was one of the pioneers of abstract art. The abstract nature of his work that exemplifies some of the concepts that Greenberg identified as being aligned with Modern art is a proclivity towards subdued colors, something which Richter was noted for doing with monochromes (especially involving the color grey). Furthermore, some of Richter's later works were purposefully designed to depict certain facets of reality that could not be perceived except by the naked eye, which certainly adheres to Greenberg's notion that Modern art strives to rely on merely the sense of the optical to convey aspects of a subject.
