Through design principles and processes, the problems of basic design that meet within the range of two dimensions, including dots, lines and faces, are visually recognizedit's a class that solves. Design elements such as shape, color, and texture, as well as unification/change, balance/harmony, symmetry/asymmetry, proportionality/contrast, etcin a plane where various design principles can be digested in mathematical or sensory ways and appropriately utilized according to the situationit enables development and development of basic design capabilities.
