With our software, Merck simplifies the search for the individual cosmetic blend for their customers, i.e. the appropriate mixture of effect pigments to create a specific color for a cosmetic application. The color preview is shown using nail polishes as an example. In total, over 900 different blends are available for selection. Through the selector, currently used in the webshop and at trade shows, customers can quickly and needs-oriented narrow down their selection.
