Webinar: Measurement of effect colors

Measurement of effect colors


In contrast to solid colors, effect finishes change their color and appearance with viewing angle and lighting conditions. Metallic finishes show a lightness travel depending on viewing angle whereas pearlescent colors also create a color flop. Additionally, special effect pigments exhibit high sparkling effects under direct illumination.


In order to objectively describe the visual impression of effect finishes two different measurement principles are needed. Attend the BYK-Gardner WEBseminar to learn more!
