Painting, in its most basic form, can be defined as "the process, art, or occupation of coating surfaces with paint for a utilitarian or artistic effect."  For some artists it is the act of applying colored substance to a surface or creating a picture with colored oils or pastels; consequently an artistic composition made by applying paints to a surface is also "a painting."
Painters have the freedom to invent their own visual language and to experiment with light and new forms, materials and techniques. In some cases, the distinction between painting and other forms of art may be blurred; for example, some artists have covered natural landscape areas such as parks or island beaches with fabric (see Christo).

We know from textual and archaeological sources that painting was practiced in China from very early times and in a variety of media. Wall paintings were produced in great numbers in the early period of China's history. 
Essentially, painting has changed very little since these times: the surfaces have evolved through rock faces, the walls of buildings, silk, paper, wood, cloth and canvas, while the range of pigments used have encompassed earths and minerals, plant extracts and modern synthetic colours. The earliest example of silk painting was excavated from the Mawangdui Tomb in central China of the Warring States Period (476-221 B.C.) The pigments have also been mixed with water and gums to make paint, and the earliest known examples of oil paints were used in Afghanistan in the seventh century, derived possibly from walnuts or the poppies which grew in the area. Oil paints were eventually introduced in Europe in the fifteenth century using linseed oil. The flexibility and durability of this new medium "played a major part in the explosion of creativity in Western painting during and after the Renaissance."

See: National Painting for painting in several countries.From the fourth century onwards the early civilizations of the Mediterranean region and Europe began to produce paintings of sufficiently consistent artistic style that art historians and archaeologists are able to distinguish which works belonged to which cultures. Egyptian artwork is highly detailed, their figures are still and appear rigid.
Few examples of Greek painting (c. 600-100 B.C.) have survived, originally painted on wood which has rotted away or buildings which have been destroyed. Its style was very influential however on the Roman style of paintings, which spread throughout the Roman Empire into the Middle East, North Africa and Europe.
Christianity brought further change to the Roman style, particularly as the "illustration of the Gospels was... necessary in order to spread the beliefs to the new converts, most of whom were illiterate. After the Roman Empire collapsed, Europe's greatest inheritance was the Roman-Christian tradition, which was heavily infused with classical ideas and Christian artistic styles. Despite some scholarly belief that the Middle Ages was a period of artistic decline, the existence of beautiful painted manuscripts and glowing altars from that period (Middle Ages Painting) suggests otherwise." Renaissance artists broke decisively from their medieval predecessors by looking to nature as their guide in the art of painting.

Movements and Schools
The movement or School that an artist is associated with is usually reflected in the style of the painting.
- Abstract Expressionism
- Academic Art
- Art Deco
- Art Nouveau
- Ashcan School
- Baroque- which commonly features scenes from the Bible
- Early Expressionism
- Lyrical Abstraction
- Neo-Pop Realism
- Op Art
- Pop Art
- Romantic Realism
- Some adhere to a rigid definition of "art", such as paintings, sculpture and other traditional genres, while others believe that art should not be strictly defined, and thus believe that anything progressive may be labeled as such.
Different types of painting are usually identified by the "medium" that carries the pigment. This affects the viscosity, miscibility, solubility, durability, flexibility and the appearance of the applied pigment. Common media include:
Paintings are not always executed using a single medium: Henry Moore, for example, used oil pastels and watercolours together, knowing that they would not mix. He would use oil pastel for the main features and then cover the paper with a watercolour wash, creating a bolder impression of the initial drawing.
Composition and design
The execution and design of a painting can be subdivided as:
- Color - Color is more than a filling in of space, as it may have a structural role to play in the composition. The painter may use it to connect areas of the painting through similarity or create contrast by difference. It can also create spatial depth, harmony and mood.
Leonardo da Vinci describes color contrast, in particular the simultaneous contrast of complementary colors, as follows: “Of different colors equally perfect, that will appear most excellent which is seen near its direct contrary blue near yellow, green near red: because each color is more distinctly seen when opposed to its contrary than to any other similar to it.”
- Space - Painters describe different kinds of space, such as primitive ("flat") space; illusionistic, ("Renaissance") space; modern space (developed from Cezanne's union of flat and illusionistic space); and all-over space, such as that used by Jackson Pollock in his drip paintings. There is also "positive" space (occupied by a form or figure) and "negative" space (loosely, the background).
- Composition - When deciding the composition of the painting, the painter will be influenced by the subject (eg. landscape, portrait, still life) and then how the forms within the subject relate to the borders of the painting. How the viewer's eye is meant to be drawn over the whole and to certain areas will also determine the composition.
The elements of design (i.e., line, color, tone, texture) are used in various ways to produce sensations of volume, space, movement, and light. The range of media (e.g., tempera, fresco, oil, watercolour, ink, gouache, encaustic, casein) and the choice of a particular form (e.g., mural, easel, panel, miniature, illuminated manuscript, scroll, screen, fan) combine to realize a unique visual image.
