Yellow 6 And Blue 1

Yellow 6 (also known as FD&C Yellow No. 6) and Blue 1 (also known as FD&C Blue No. 1) are synthetic color additives. They are manufactured from petroleum-based raw materials through chemical processes.

These dyes are added to foods and beverages to impart a yellow-orange (Yellow 6) or bright blue (Blue 1) color. They are commonly found in candies, soft drinks, baked goods, and some dairy products like yogurt.

Yellow 6 and Blue 1 are approved by the FDA as food additives. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 6 and Blue 1. Both dyes have been evaluated by JECFA, which has set an acceptable daily intake. EFSA has also evaluated these dyes. Some studies have suggested a link between synthetic food dyes and hyperactivity in some children, while other research has not found a consistent connection.
