Performance & Formulation Insights for Fiesta Gemini GR-37

Dynamic Green-to-Red Color Travel

Fiesta Gemini GR-37 is a color-travel effect pigment that shifts between green and red as the viewing or lighting angle changes. Built on a synthetic fluorphlogopite (synthetic mica) substrate with a silica multilayer and iron oxides, it produces a striking duochrome flip rather than a single flat color.

Key Technical Advantages in Formulation

With a particle size of roughly 50–200 microns, it delivers bold, light-catching sparkle and a pronounced color shift, ideal for statement, multi-dimensional effects.

The synthetic mica and silica multilayer structure creates the optical interference that drives the color travel, while keeping a clean, consistent, high-purity substrate.

Key Formulation Benefits

• Dynamic color travel: shifts between green and red with angle.
• Bold, large-flake sparkle: 50–200 µm for high impact.
• Maximum clean profile: ferro-free, carmine-free, and titanium-dioxide free.
• Synthetic mica substrate: consistent, high-purity color performance.
