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.
Key words: Cu-Mn-Zn; chromaticity; color; regression
