Colors: Icing And Decorations May Include Blue 1

Blue 1, also known as Brilliant Blue FCF, is a synthetic food coloring. It is a bright blue dye produced from petroleum. This color additive is widely used to impart a blue hue to various food products.

Manufacturers add Blue 1 to foods and beverages to achieve a blue color. It is frequently found in items like ice cream, frozen desserts, candies, beverages, and baked goods, especially in icings and decorations.

In the United States, Blue 1 is an FDA-approved color additive. JECFA has evaluated Blue 1 and set an acceptable daily intake. EFSA has also evaluated this additive. Some studies have explored a potential link between synthetic food dyes and hyperactivity in some children, though evidence is mixed and regulatory bodies generally consider the dye safe at typical intake levels. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue 1.
