Throughout the history of Korean painting, there has been a constant separation of monochromatic works of black brushwork on very often mulberry paper or silk; and the colourful folk art or min-hwa, ritual arts, tomb paintings, and festival arts which had extensive use of colour.
Colour theory has been used over formal perspective, and there has yet to be an overlap between painterly art and pop-graphics, since the primary influence on painters is ceramics art.
