Drawing is one of the major forms of expression within the visual arts. It is generally concerned with the marking of lines and areas of tone onto paper, where the accurate representation of the visual world is expressed upon a plane surface. Traditional drawings were monochrome, or at least had little colour, while modern colored-pencil drawings may approach or cross a boundary between drawing and painting. In Western terminology, drawing is distinct from painting, even though similar media often are employed in both tasks. (WIKI)
