Quinacridone Gold is a high performance pigment. It lacks brightness and cleanliness in tints, and it may disperse unevenly. It has an average drying time. Quinacridone pigments have relatively low tinting strength in general. For this reason, quinacridone colors are often expensive, because more pigment is required in the formulation.
Quinacridone Gold has excellent lightfastness and is considered the most lightfast pigment in its shade range.
Quinacridone gold is not considered toxic. Overexposure to quinacridone pigments may cause skin irritation. Quinicridone pigments contain a compound found to be a skin, eye, and respiratory irritant.
Although quinacridone compounds became known in the late 19th century, methods of manufacturing so as to make them practical for use as commercial pigments did not begin until the 1950s. Quinacridone pigments were first developed as coatings for the automotive industry, but were quickly adopted by artists.
