Painting is a form of art in which pigments or other coloring materials are applied to a surface to produce images, patterns, or expressive arrangements. The term refers both to the activity and to its resulting objects. Paintings may represent visible things, convey narratives or beliefs, explore color and form, or combine these purposes. Although commonly associated with flat surfaces, painting also occurs on architectural elements, vessels, and three-dimensional objects. Its boundaries overlap with drawing, decoration, and mixed-media practices.
Materials and techniques
Most paints consist of a pigment, which supplies color, dispersed in a binder that holds the particles together and attaches them to a support. Water or solvents may adjust working consistency. Supports include rock, plaster, wood, cloth, paper, and metal; their texture and absorbency influence the result. Artists often prepare a support with a ground that provides a suitable painting surface.
Different binders produce distinct working properties. Oil painting uses drying oils, such as linseed oil, and permits blending, transparent layers, and substantial revisions. It became widely established in European painting during the fifteenth century, although oil-based techniques existed earlier. Watercolor typically combines pigments with a water-soluble binder and often uses the paper's brightness beneath transparent washes. Gouache generally produces more opaque passages.
In fresco, pigments suspended in water are applied to fresh lime plaster and become incorporated into its surface as it sets. Egg tempera uses an emulsion, commonly based on egg yolk, and is suited to precise, relatively quick-drying strokes. Acrylic painting, widely adopted during the twentieth century, uses synthetic polymer binders and can range from thin washes to thick, textured applications.
Paint can be brushed, poured, sprayed, scraped, or applied with fingers and palette knives. Glazing builds transparent layers, while impasto leaves raised deposits. Technical choices affect not only appearance but also drying, aging, and durability.
Historical development
Painting survives from prehistoric communities in cave and rock-shelter imagery across several continents. Mineral colors and charcoal were used to depict animals, human figures, and signs. The purposes of these images cannot always be established, and surviving examples represent only a fraction of early image-making.
In ancient Egypt, painted tombs and temples combined figures, inscriptions, and symbolic colors within established conventions. Wall paintings from the Roman Empire, notably those preserved around Pompeii, include architectural illusions, mythological scenes, and everyday subjects. Survival is uneven: durable walls and protected burial settings preserve more evidence than exposed or perishable supports.
During the European Renaissance, painters developed systematic approaches to spatial representation, anatomy, and the observation of nature. Linear perspective offered a geometrical method for constructing apparent depth from a fixed viewpoint. Artists including Leonardo da Vinci investigated light, atmosphere, and gradual transitions of tone. Workshops, religious commissions, and court patronage shaped production.
Painting also developed through distinct, interconnected traditions outside Europe. Chinese brush painting shared tools and principles of brushwork with Chinese calligraphy. Landscape became particularly prominent during the Song dynasty, alongside figure and flower-and-bird subjects. Handscrolls and hanging scrolls created viewing conditions different from framed easel pictures.
Indian painting encompasses murals, manuscript illustrations, courtly works, and other regional practices. Buddhism supported mural traditions across parts of Asia, while Persian and South Asian miniature painting cultivated detailed imagery in books and albums. Painting in Indigenous societies includes rock art, ceremonial imagery, and decoration of objects and built environments; its meanings depend on particular cultural settings.
Representation and visual organization
Painters organize line, shape, color, tonal value, texture, and space into compositions. Overlap, changes of scale, shading, and atmospheric effects can suggest depth without requiring mathematical perspective. Other traditions emphasize flattened space, multiple viewpoints, or hierarchical scale, in which a figure's size expresses importance rather than physical distance.
Subject categories include portraiture, landscape painting, still life, and religious or historical scenes. These categories are not universal or mutually exclusive. A portrait may also contain a landscape, and apparently ordinary objects may carry symbolic meanings.
Abstract art reduces or departs from recognizable representation. Some abstract paintings transform observed subjects; others use nonrepresentational shapes, gestures, or color relationships. Interpretation therefore involves both depicted content and material decisions, including scale, surface, and visible brushwork.
Modern and contemporary practices
During the nineteenth century, photography introduced another means of producing images. Painters responded in varied ways rather than simply abandoning representation. Impressionism emphasized changing light, contemporary subjects, and conspicuous brushwork. Portable materials also facilitated work outdoors.
Twentieth-century modernism encompassed movements that reconsidered pictorial space and established conventions. Cubism fragmented forms and combined different aspects of a subject within one image. Other painters explored expressive distortion, geometric abstraction, or the physical act of applying paint.
Contemporary painting accommodates these approaches alongside figurative work, installation, and hybrid media. Artists may combine painted surfaces with photographs, printed imagery, textiles, or digital processes. Digital painting uses software and electronic input devices to construct images, replacing or supplementing physical pigments with editable color data.
Preservation and study
A painting's condition depends on interactions among its support, ground, paint layers, and any varnish. Humidity changes may deform wood or canvas; light can alter sensitive colorants; paint may crack or detach. Earlier repairs and restorations can also affect appearance.
Museums and conservation specialists document these changes as part of preserving cultural heritage. Microscopy, infrared imaging, X-radiography, and spectroscopy can reveal underlying designs, identify materials, and distinguish alterations. Technical evidence is interpreted alongside documentary records and stylistic analysis, since no single test establishes a painting's authorship or history in every case.
