Painting is a visual art, which is characterized by the practice of applying paint, pigment, color or other medium to a solid surface (called "matrix"^[1] or "support").^[2] The medium is commonly applied to the base with a brush. Other implements, such as palette knives, sponges, airbrushes, the artist's fingers, or even a dripping technique that uses gravity may be used. One who produces paintings is called a painter.

In art, the term "painting" describes both the act and the result of the action (the final work is called "a painting"). The support for paintings includes such surfaces as walls, paper, canvas, wood, glass, lacquer, pottery, leaf, copper and concrete, and the painting may incorporate other materials, in single or multiple form, including sand, clay, paper, cardboard, newspaper, plaster, gold leaf, and even entire objects.

Painting is an important form of visual art, bringing in elements such as drawing, composition, gesture, narration, and abstraction.^[3] Paintings can be naturalistic and representational (as in portraits, still life and landscape painting--though these genres can also be abstract), photographic, abstract, narrative, symbolist (as in Symbolist art), emotive (as in Expressionism) or political in nature (as in Artivism).

A significant share of the history of painting in both Eastern and Western art is dominated by religious art. Examples of this kind of painting range from artwork depicting mythological figures on pottery, to Biblical scenes on the Sistine Chapel ceiling, to scenes from the life of Buddha (or other images of Eastern religious origin).
