While blue is the most popular color around the world, not all blues are created equal and or belong into the food supply. The Rapid Alert System for Food and Feed in Europe mentioned a case of unauthorized food dye Sudan Blue II in a roasted corn snack food. Sudan Blue II, also known under the name Solvent Blue 35, is used to dye oils, solvents, alcohols, esters, hydrocarbon derivatives and other industrial chemicals, and is classified as carcinogenic and harmful to humans and the environment.
