Yellow #6 And Blue #2

Yellow #6 (also known as Sunset Yellow FCF) and Blue #2 (also known as Indigotine or Indigo Carmine) are synthetic color additives. They are petroleum-based dyes created through chemical synthesis.

These dyes are added to foods to impart yellow and blue colors, respectively, or to create other shades when mixed. They are commonly found in candies, snacks, beverages, and baked goods to enhance visual appeal.

Yellow #6 and Blue #2 are FDA-approved color additives. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, which includes both Yellow #6 and Blue #2. Both dyes have been evaluated by JECFA and EFSA, and both bodies have set acceptable daily intakes, concluding they are safe at these levels. However, there have been ongoing discussions and mixed evidence regarding a potential link between synthetic food dyes and hyperactivity in some children.
