Abstract

The first colour diagram of the gold-silver-copper system was published over 30 years ago by Josef Leuser. This was based on visual, and therefore subjective, colour assessment. Renewed interest in the colour characteristics of gold alloys, as well as the development of improved instrumentation for their measurement, have stimulated recent research on the subject. This has now progressed to the point where objective, quantitative information on the relationship between alloy colour and composition is available.
