Descripción
A natural dark pink madder colorant extracted from madder roots with an acid, then the precipitate, primarily pseudopurpurin, is redissolved in alum then reprecipitated with calcium carbonate to produce a pink lake. It became popular as an artist pigment after the madder plant was imported to Holland in the 16th century.
