Abstract: Excess capacity is a major problem faced by the engineering equipment industry, which
can be solve this problem by design. This article uses of the basic theory of color, color psychology,
kansei engineering, market research, statistical analysis and other methods, to solve the problem of
color matching and color matching on construction machinery, and getting three kinds of color
matching scheme (numbered A4-4, B2-4, C2-4) and then, taking excavator as an example, the color
scheme is verified, achieving the desired results. Hope to provide reference for the coating design of
construction machinery products.

Key words: color image, construction machinery, coating design, color selection
