Multi-image Evaluation of Product Color Design based on Grey Relational Analysis

To realize multi-image scheme selection of product color design, the grey relational analysis method was introduced into product color evaluation process. Through multi-image acquisition of product color design, users were asked to give their scores of each color scheme according to target multi-image, which were used to establish decision matrix. Ideal solution was acquired by standardizing decision matrix. Based on grey relational analysis method, the relation between product color schemes and ideal solution was calculated. Finally, the multi-image scheme selection of electric scooter color design was taken as an example to verify the efficiency of the proposed method.
