Painting is the practice of applying paint, pigment, color or other medium to a support surface. In art, the term describes both the act and the result, which is called a painting. Paintings may have support surfaces such as walls, paper, canvas, wood, glass, lacquer, clay or concrete. Painting is a mode of expression, and the forms are numerous. Drawing, composition or abstraction and other aesthetics may serve to manifest the expressive and conceptual intention of the artist. Paintings can be naturalistic and representational (as in a still life or landscape painting), photographic, abstract, be loaded with narrative content, symbolism, emotion or be political in nature.
