What term describes large canvases filled with blocks of color? Color field painting is the standard term.

Color field painting describes an abstract style in which broad areas of color dominate the canvas. The color may appear as a flat, solid expanse or as a stained, softly merging layer, but the composition generally minimizes recognizable imagery and emphasizes the emotional and visual force of color itself.

The style emerged in New York during the 1940s and 1950s in close relationship with Abstract Expressionism. Mark Rothko, Clyfford Still, and Barnett Newman are among its best-known practitioners. Their work often uses large scale and simplified structures to create an immersive experience rather than to depict a scene or object.

The phrase is sometimes confused with action painting, another major direction within Abstract Expressionism. Action painting foregrounds gesture, brush movement, drips, and visible physical activity; color field painting generally reduces those marks in favor of sustained color relationships and an overall unified surface. “Lyrical abstraction” is a related but broader label, not the most precise answer for large color-dominated fields.
