What the label is naming
Red 40 is the US name for Allura Red AC. Labels may shorten it to Red 40, spell out FD&C Red No. 40, or use the European code E129 and Colour Index 16035. Red 40 Lake is the same dye on a substrate and still matches.
Where it hides
Fruit drinks, kids' yogurts, candy coatings, strawberry fillings, and cheese-flavored snacks. A red picture on the package is not a match; the ingredient line is.

Questions
Does a red package picture count?
No. AisleSwap highlights the printed ingredient span only. It does not judge color from a photo of the front of the box.
