Colorfield- A movement started in the US American East Coast in the mid-late 40's. While most works of art has a thing for it's subject -person, road, tree, building, baskets of slowly rotting fruit- Colorfiled's subject is the enviorment itself, not an object placed in an enviornment. As implied by it's name, the environments are bold strokes of color. Notable Colorfield artists are Mark Rothko, Clyford Still, and Helen Frankenthaler. Some historians speculate Colorfield is a large influence in the Abstract Expressionism.
