What it is
Yellow 6 (Sunset Yellow FCF) and Yellow 5 (Tartrazine) are synthetic food dyes made from petroleum. They are used to give foods and drinks a yellow to orange color.
Why it's used
Manufacturers add these dyes to create appealing colors in a wide range of products, such as cakes, snack cakes, processed cereals, and various beverages. Their primary function is to provide a consistent and vibrant color.
Health notes
Both Yellow 5 and Yellow 6 are approved by the FDA as color additives for use in food. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes Yellow 5 and Yellow 6. JECFA has evaluated both dyes and set an acceptable daily intake. EFSA has also evaluated these dyes. There has been mixed evidence regarding a possible link between synthetic food dyes, including Yellow 5 and Yellow 6, and hyperactivity in some children.
