After that Chosunpainting has largely produced and became a main stream genre of North Korea Art. Special feature and the manner shown in North Korea Art can summarized as below. Painting has to express bright and clear color according to the original color of the feature based on realistic attitude, using blank space and aiming tender unity excluding rough, contrasty elements. North korea kept this principle that Chosunpainting has to be based on nationalized with distinctive procedure with the rule of North Korea Art indicated above. Therefore so called nationalized form of North Korea art is determined by color and figure with using the blank space and bright background.
