Research on Color Design and Evaluation Method of Cultural Creative Products Based on Color Harmony Theory

With the improvement of people's quality of life and the love for various national cultures, the conventional product color design created by industrial designers combining their own knowledge, experience and other individual knowledge is not enough to meet the aesthetic needs of consumers to obtain cultural attributes. Compared with conventional product color design, the effective communication of cultural images is the core of cultural creative product color design. In this paper, for the purpose of expressing multicultural images of color design of cultural creative products, we propose a coupling and correlation analysis method of color beauty and visual beauty, and study the mapping relationship between color beauty and visual beauty on color image based on least square regression analysis. The mapping relationship is used to obtain the key parameters that affect the dynamic changes of color images. Finally, a quantitative model of product color dynamic reconciliation is established, and a product color design and evaluation method based on cultural image constraints is proposed. Based on the above method research, the color design of the ultraviolet lamp is used as an example to verify the effectiveness of the proposed method.
