Abstract: There are great diversity in the productions’ colors and RGB model used in computer system.In order to resolve this confliction，this paper introduces a feasible method，which can convert the actual color of the production into the RGB color model based on the color analyzer.Then，the system of the mathematical model-related on the R，G and B values for the CIE 1931-RGB and computer display is established.Finally，this paper validates the algorithm with some experiments.These data show that the color conversion is a scientific method for industrial design，and it also provides a simple way for color design.
