Hunan University of Science and Technology，Xiangtan 411201，China)Abstract: For mining dump truck lack of color design, based on product identity theory, the recognition of color painting of mining dump truck was analyzed, the concept of product identification color design was put forward. Through the analysis of the Caterpillar product system of dump truck color design causes, the bearing surface characteristics were obtained, that include elements of color, color combinations, color graphics information, the design model was established to use. in color design of XEMC mining dump truck, the feasibility of the initial proof method was proved.
