What it is
Blue 1 and Yellow 6 are synthetic color additives made from petroleum. Blue 1 provides a bright blue hue, while Yellow 6 gives an orange-yellow color.
Why it's used
These dyes are used to add or restore color to a wide variety of processed foods and beverages. They are commonly found in candies, cereals, baked goods, snacks, and soft drinks to make them more visually appealing.
Health notes
Blue 1 and Yellow 6 are approved by the FDA as food additives. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue 1 and Yellow 6. Concerns have been raised about a possible link between synthetic food dyes and hyperactivity in some children; however, scientific evidence on this topic is mixed, and a conclusive link for the general population has not been established. Both JECFA and EFSA have evaluated these dyes and set acceptable daily intakes.
