The works of German graphic design masters have strong tension. This kind of "force field" does not come from the exaggeration of modeling and gorgeous colors, but from the proper spatial slicing and reorganization, which brings the visual function of the plane to the extreme. Simple modeling and pure color, however, through rational and experimental treatment of layout and space, have a strong impact on the viewer's vision and psychology, making the monotonous picture stiff and aggressive, and after conveying information, let the viewer realize something worth repeating. Uwe Lesch once said, "The best designer has the biggest wastebasket."
