The Chemistry of Food Colorings

Why go artificial? Why bother with artificial, or synthetic, food colorings? Aren’t there enough natural colors to go around? A big reason to go artificial is cost. Synthetic dyes can be mass-produced at a fraction of the cost of gathering and processing the materials used to make natural colorings. Another reason is shelf life.
