Painting means the practice of using paint, pigment, color or other medium to a surface (support base). People usually apply the medium to the base with a brush. At the same time, other tools such as knives, airbrushes, sponges could be used too. In terms of art, the painting depicts not only the act, but also the result of the action. But, the painting can be also applied outside the art world as a common business between builders and craftsmen. The surfaces like wall, paper, wood, glass, clay, canvas, lacquer, copper and many other materials such as sand, gold leaf as well as real objects can equally support the paintings.
It can be said that the painting is a creation expression pattern whose forms are various. The practitioner is able to use composition, drawing or abstraction and other aesthetics to show the expressive and conceptual thoughts. In a landscape painting, abstract painting, realistic painting, and portrait or in a still life, the painting could be very naturalistic and expressive with the narrative content, inner emotions or symbolic political meanings in the real life.
Among the eastern and western art world, spiritual ideas remain dominant a large portion of the painting history. Just as pitch and rhythm are the essentials of music, the color and tone are exactly the soul of painting. Although we consider the color quite subjective, the color still can produce some psychological influences which are easily observable and significantly different from one culture to the next one. From the perspective of the western people, the black means mourning. While for the oriental people, white has the above meaning. A painter could not roughly divide all the colors into the basic and derived colors such as red, yellow, blue, gray, etc. Therefore many painters and artists have written their own color theories. They wish to make colors more generalized and clearly defined.
