May Contain: Blue 1

Blue 1, also known as Brilliant Blue FCF, is a synthetic blue food coloring. It is made from petroleum byproducts through a chemical process. It is approved for use in the United States and many other countries.

Manufacturers add Blue 1 to foods and beverages to provide a blue color. It is commonly found in ice cream, frozen yogurt, candy, baked goods, and drinks. It is often used in combination with other colors to create a wider range of shades.

Blue 1 is an approved food additive by the FDA. In 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue 1. The European Food Safety Authority (EFSA) has also evaluated Blue 1 and established an acceptable daily intake. Some studies have suggested potential links between artificial food colorings and hyperactivity in children, though evidence is mixed and regulatory bodies have not established a causal link at typical consumption levels.
