Abstract: The color of Cu-Mn-Zn alloys is quantitatively researched using the CIE L^*a^*b^* color system. The color parameters such as L^*, a^* and b^* are employed to describe the color and are measured by a spectrophotometer. Based on the color data of 46 experimental alloys, a series of formulae are established to correlate color parameters changed with the alloy composition. Therefore, the color of the ternary Cu-Mn-Zn alloys can be calculated and forecast easily. The results show that Mn plays a more important role in the color of Cu-Mn-Zn alloys than Zn does. In particular, the chroma values of ternary Cu-Mn-Zn alloys mainly depend on the Mn content.
