    Lake colors are produced by reacting dyes, typically azo dyes, with a metallic salt to form an insoluble precipitate. The most common metallic salts used are aluminum, calcium, barium, and chromium salts. The anionic groups on the dye, such as sulfonate or carboxylate groups, bind to the metallic cation to form the pigment. The color of the resulting pigment depends on the particular dye used. Lake colors are often named after the dye they are made from, such as Red 40 Lake or Blue 1 Lake. #foodcolors #pharmaceutical colors #synthetic colors
