Painting is the practice of applying color to a surface (support) such as, e.g. paper, canvas, wood, glass, lacquer or concrete. However, when used in an artistic sense, the term "painting" means the use of this activity in combination with drawing, composition and other aesthetic considerations in order to manifest the expressive and conceptual intention of the practitioner.

Painting is used as a mode of representing, documenting and expressing all the varied intents and subjects that are as numerous as there are practitioners of the craft. 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. A large portion of the history of painting is dominated by spiritual motifs and ideas; sites of this kind of painting range from artwork depicting mythological figures on pottery to biblical scenes rendered on the interior walls and ceiling of The Sistine Chapel to depictions of the human body itself as a spiritual subject.

In 1829, the first photograph was produced. From the mid to late 19th century, photographic processes improved and, as it became more widespread, painting lost much of its historic purpose to provide an accurate record of the observable world. There began a series of art movements into the 20th century where the Renaissance view of the world was steadily eroded, through Impressionism, Post-Impressionism, Fauvism, Expressionism, Cubism and Dadaism. Eastern and African painting, however, continued a long history of stylization and did not undergo an equivalent transformation at the same time.

Modern and Contemporary Art has moved away from the historic value of craft and documentation in favour of concept; this has led some to say that painting, as a serious art form, is dead, although this has not deterred the majority of artists from continuing to practise it either as whole or part of their work.
