Abstract: In view of the fuzziness and uncertainty of consumers to color image during product color design, a product color fuzzy optimum design method with consideration of uncertain color image is established. This actual problem can be converted into the optimum solution fuzzy searching whose solution space is given. Meanwhile, the fuzzy design model of product color is constructed. The model is to be solved by particle swarm optimization in order to obtain a series of optimum color scheme solutions. Users select the most satisfactory one, so the product color scheme which meets consumers’ image requirement can be obtained. Through a color design case of construction machine, it is verified that this method can effectively improve the uncertainty problem encountered in the intelligent searching of product color. Compared with traditional color intelligent design method, this method increases the generation rate of satisfactory solution, thus improving the success rate of product color design.
