If you’ve ever glanced at an ingredient label and seen something like “Red 40” or “Yellow 5,” you’ve spotted a numbered dye. These artificial food colorings are synthetically made and used in everything from candy and cereal to toothpaste, drinks, and even medicine.

Numbered dyes are part of a group of food additives certified by the U.S. Food and Drug Administration (FDA) and identified by both their common names (like Red 40) and regulatory designations (like FD&C Red No. 40).

Common Numbered Dyes

• Red 40 (Allura Red AC) – The most commonly used dye in the U.S.
• Yellow 5 (Tartrazine) – Often found in chips, drinks, and candies
• Blue 1 (Brilliant Blue FCF) – Popular in frostings, slushies, and yogurts
• Yellow 6, Red 3, Blue 2, Green 3 – Also commonly used across the food and pharmaceutical industries

These dyes are petroleum-derived and are primarily used to make food more visually appealing, especially to children.
