I don’t think this is a science or safety issue, it’s an issue with bad ingredient labeling. They should name these numbered dyes something more understandable. “Red dye 4” sounds pretty sketchy when they could say “Cochineal extract for coloring”. People can reject the product because the ingredients include a bug derived coloring rather than fear of the unknown “red dye” invented by their imagined evil food scientists.
