With the development of new effect pigments also comes the development of new measurement methods. This includes the multi-angle measurement of aluminum and interference pigments, as well as the description of perception effects. Thus, the various DIN, VDA and ASTM committees discuss these methods and how these phenomena can be explained. Based on these discussions, measuring instruments are developed that can be used in the workflows of relevant industries. The multitude of innovations with regard to pigment – but also in coatings and application areas – influence how a new standard color is created and what aspects are to be considered. Eight golden rules have been compiled to ensure effective color creation.
In most cases, modern automotive coatings have an effect that changes either the lightness or both the lightness and color. Depending on the location of the illumination and the location of observation, geometries result that relate to the appropriate angle.
