People associate certain colors with certain flavors, and the color of food can influence the perceived flavor in anything from candy to wine.[2] Sometimes the aim is to simulate a color that is perceived by the consumer as natural, such as adding red coloring to glacé cherries (which would otherwise be beige), but sometimes it is for effect, like the green ketchup that Heinz launched in 1999.

[edit]Regulation
Food colorings are tested for safety by various bodies around the world and sometimes different bodies have different views on food color safety. In the United States, FD&C numbers (which indicate that the FDA has approved the colorant for use in foods, drugs and cosmetics) are given to approved synthetic food dyes that do not exist in nature, while in the European Union, E numbers are used for all additives, both synthetic and natural, that are approved in food applications. The food colors are known by E numbers that begin with a 1, such as E100 (turmeric) or E161b (lutein).[5] Most other countries have their own regulations and list of food colors which can be used in various applications, including maximum daily intake limits.
Natural colors are not required to be certified by a number of regulatory bodies throughout the world, including the United States FDA. The FDA lists "color additives exempt from certification" for food in subpart A of the Code of Federal Regulations - Title 21 Part 73. However, this list contains substances which may have synthetic origins. FDA's permitted colors are classified as subject to certification or exempt from certification, both
