Painting, meant literally, is the practice of applying color to a surface (support) such as 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.

Hegel recognized the failure of attaining a universal concept of beauty and in his aesthetic essay wrote that Painting is one of the three "romantic" arts, along with Poetry and Music for its symbolic, highly intellectual purpose. Painters who have written theoretical works on painting include Kandinsky and Paul Klee. Kandinsky in his essay maintains that painting has a spiritual value, and he attaches primary colors to essential feelings or concepts, something that Goethe and other writers had already tried to do.

Iconography has also something to say about painting. The creator of this discipline, Erwin Panofsky, tries to analyse visual symbols in their cultural, religious, social and philosophical depth to attain a better comprehension of mankind's symbolic activity.
