Abstract: Automatic mapping mechanism of color scheme from plane image to product 3D product model is researched. Color scheme is obtained from plane image by using color merging and main color extracting techniques, and based on this, product color scheme solution space is constructed. Under the premise of considering the factors such as color number, proportion, and random originality, the color scheme is mapped from the plane image to the surface of 3D product model, and the color schemes are demonstrated in visual way for the designer to choose. Interactive genetic algorithm is used to seek for the optimal scheme. From the scheme codes chosen by the designer, the program analyzes and calculates the implicit information about designer’s imagery, and uses it to construct the fitness evaluation function so as to push forward the optimization of scheme. Verification of the design method is carried out in the design of exterior colors of product, in which the automatic extraction of color scheme, mapping and design optimization are realized
