Abstract: The changing law of the color characteristics of Cu-Zn-Al alloys with their compositions has been researched systematically and quantitatively. The results show that with an increase in Zn and Al content, the lightness value and yellow content of an alloy increase first to a certain ex-tent and then decrease, while the red content decreases first to a certain extent and then increases; the alloy color changes from copper red to golden yellow, yellow, grey brown , pink , and silver grey. By adjusting Zn and Al content, a series of alloys with 14 K or 18 K alloy colors can beobtained, but those with 24 K gold color can not be obtained.
