Art Informel is a French term referring to the gestural and improvisational techniques common in abstract painting during the 1940s and 50s. It encompasses various styles that dominated these decades, characterized by informal, spontaneous methods. Artists used this term to describe approaches that moved away from traditional structures and embraced more expressive, unstructured techniques.

Colour Field Painting is an abstract style characterized by large areas of a single color or simple, solid colors. The term was first used in the 1950s to describe the work of three American Abstract Expressionist painters—Barnett Newman, Mark Rothko, and Clyfford Still. Their work emphasized the emotional power of color and the creation of vast, meditative spaces through expansive color fields.

Also referred to as Earth Art, Earthworks, or Environmental Art, Land Art is a sculptural movement that involves creating artworks that integrate conceptual or physical elements of the earth or landscape into the finished piece. These works often interact directly with the environment, using natural materials and settings to explore themes related to nature, place, and time
