Question

Quizplus · Accepted Answer

The main subject of the postwar New York School artists was the act of painting itself, often referred to as "painting about painting." They focused on exploring and pushing the boundaries of the medium, its materials, and techniques, rather than any specific subject matter such as life on the streets or appropriation. Optical phenomena played a role in some of the artists' works, but it was not the main subject.
