"CSPI is urging parents who believe their children are harmed by food dyes to file reports online at http://www.cspinet.org/fooddyes/form.html. The nonprofit nutrition and food-safety watchdog group will periodically forward the reports to the FDA, which denies that dyes cause any problem whatsoever. CSPI wants to hear from parents who believe that food dyes impair their children's behavior, as well as parents whose kids' behavior improved when food dyes were eliminated from their diets." This is a link to report what you've seen in your kids. http://www.cspinet.org/fooddyes/form.html. There are a few articles on this website, also linking food dyes with excema and asthma if you take some time to go through some of the articles.
