red dye

Scarlet food additive

Red dye is any coloring agent that produces red hues.

The term often refers to synthetic food colorings—particularly Red No. 40, used in candies, beverages, and processed foods.

The label listed red dye as an ingredient.

Red dyes also appear in textiles, cosmetics, and hair products.

Some people avoid certain red dyes due to concerns about allergic reactions or hyperactivity in children.
