What the label is naming
Yellow 5 is tartrazine. Labels use Yellow 5, FD&C Yellow No. 5, tartrazine, E102, or CI 19140. The number boundary stops Yellow 5 from matching a longer number such as Yellow 50 or Yellow 56.
Where it hides
Pickles, powdered drink mixes, macaroni dinners, candy, and some mustards that do not rely on turmeric alone. Turmeric and annatto are not aliases.

Questions
Will Yellow 5 match inside Yellow 56?
No. The pattern requires a boundary after the digit 5 so a longer color number is not clipped.
