Model of product color evaluation based on esthetics principle

The color evaluation of product depends on one's subjective judgment nowadays. The future of the product is usually controlled by personal experience and taste. According to the aesthetic psychology, principles of esthetics were combined with technology of computer graphics. The Style of product's color was recognized based on people's sense of color in visual psychology. Product's color was analyzed according to four principles of esthetics including symmetry and balance, contrast and harmony, diversification and unification, rhythm and cadence. The weight of principles was decided by the style. The model of external quantitative analysis of product's color is built and the result is evaluated by fuzzy arithmetic. The practical experiment proves the validity of this model.
