During the past 20 years, many changes have occurred in the color measurement systems, due to new effect pigments. Both effect pigment suppliers including the paint industry and manufacturers of color measurement systems have been affected by these changes. MERCK, as the leading manufacturer of effect pigments, has in recent years played a significant part in promoting the development of color measurement equipment.
