Color FD&C Blue #1

Color FD&C Blue #1, also known as Brilliant Blue FCF, is a synthetic blue food coloring. It is manufactured from petroleum byproducts. It provides a bright blue hue to foods and beverages.

Manufacturers add FD&C Blue #1 to provide or enhance the blue color in a variety of foods and beverages. It is commonly found in dairy products like ice cream and yogurt, baked goods, candies, and beverages such as sports drinks and fruit juices.

FD&C Blue #1 is an approved food additive by the FDA. The FDA has established specifications for its purity and permitted uses. Some studies have explored potential links between artificial food colorings and hyperactivity in children, but the evidence is mixed and not conclusive. JECFA and EFSA have evaluated this color additive. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes FD&C Blue #1, though specific timelines for removal from the market are still being determined.
