People associate certain colours with certain [[Flavor (taste)|flavours]], and the colour of food can influence the perceived flavour in anything from [[confectionery|candy]] to [[wine]].<ref>{{cite journal |author=Jeannine Delwiche |title=The impact of perceptual interactions on perceived flavor |journal=Food Quality and Preference |year=2003 |volume=14 |issue=2 |pages=137–146 |doi=10.1016/S0950-3293(03)00041-7 |url=http://www-fst.ag.ohio-state.edu/Pubs/2004/delwiche-fqap1.pdf |url-status=dead |archive-url=https://web.archive.org/web/20130228041745/http://www-fst.ag.ohio-state.edu/Pubs/2004/delwiche-fqap1.pdf |archive-date=2013-02-28 |citeseerx=10.1.1.103.7087 }}</ref> Since orange is popularly associated with good flavour, many companies add orange [[food colouring]] to improve the appearance of their packaged foods. Orange pigments and dyes, synthetic or natural, are added to many orange sodas and juices, cheeses (particularly [[cheddar cheese]], [[Gloucester cheese]], and [[American cheese]]); snack foods, butter and margarine; breakfast cereals, ice cream, [[yoghurt]], jam and candy. It is also often added to children's medicine, and to [[chicken feed]] to make the [[egg yolk]]s more orange.

The United States Government and the [[European Union]] certify a small number of synthetic chemical colourings to be used in food. These are usually [[aromatic hydrocarbon]]s, or [[azo dyes]], made from petroleum. The most common ones are:
*[[Allura red AC]], also known as Red 40 and [[E number|E129]].
*[[Sunset Yellow FCF]], also known as Yellow 6 and [[E number|E110]].
*[[Tartrazine]], also known as Yellow 5 and [[E number|E102]]. A dye used in soft drinks such as [[Mountain Dew]], [[Kool-Aid]], chewing gum, popcorn, breakfast cereals, cosmetics, shampoos, eyeshadow, blush, and lipstick.
*[[Orange B]] is approved by the US [[Food and Drug Administration]], but only for hot dog and sausage casings.
*[[Citrus Red 2]] is certified only to colour orange peels.
Because many consumers are worried about possible health consequences of synthetic dyes, some companies are beginning to use natural food colours. Since these food colours are natural, they do not require any certification from the Food and Drug Administration. The most popular natural food colours are:
*[[Annatto]], made from the seeds of the [[achiote]] tree. Annatto contains [[carotenoid]]s, the same ingredient that gives carrots and other vegetables their orange colour. Annatto has been used to dye certain cheeses in Britain, particularly [[Gloucester cheese]], since the 16th century. It is now commonly used to colour American cheese, snack foods, breakfast cereal, butter, and margarine. It is used as a body paint by native populations in Central and South America. In India, women often put it, under the name ''[[sindoor|sindūra]]'', on their hairline to indicate that they are married.
*[[Turmeric]] is a common spice in the Indian subcontinent, Persia and the Mideast. It contains the pigments called [[curcuminoid]]s, widely used as a dye for the robes of Buddhist monks. It is also often used in curry powders and to give flavour to [[mustard (condiment)|mustard]]. It is now being used more frequently in Europe and the US to give an orange colour to canned beverages, ice cream, yogurt, popcorn and breakfast cereal. The food colour is usually listed as E100.
*[[Paprika oleoresin]] contains natural carotenoids, and is made from [[chili pepper]]s. It is used to colour cheese, orange juice, spice mixtures and packaged sauces. It is also fed to chickens to make their [[egg yolk]]s more orange.
