If of

In the confectionery industry, candies are normally colored with water-soluble colorants, if no iron oxide pigments are available to obtain a yellow or brown color or if no titanium dioxide is available for a white color. When consuming candies, the tongue of the consumer appears colored. This effect can be considered acceptable for candies, but it is not for high-priced drugs. For the coloration of capsules, the above mentioned pigments are one alternative; another alternative is lacquers. Lacquers are used in the manufacture of gelatin capsules and for suppositories.
