The colors are Tartrazine (E102), Quinoline Yellow (E104), Sunset Yellow (E110), Carmoisine (E122), Ponceau 4R (E124) and Allura Red (E129).
Any food or drink containing one or more of the six colors-except drinks with more than 1.2% alcohol-must provide the warning on the label that the color “may have effects on activity and attention in children.” Food and drink products produced before July 20 can continue to be marketed, but any products manufactured after that date must have the new markings.
