Fire Opal
Also known as: Coquelicot, Chéng Hóng Sè Orange, Electric Orange, Fēi Hóng Scarlet
Fire Opal is what happens when red turns medium and vivid. The effect is bold and energetic, made for sale banners and sportswear. Match it with cyan accents when the design calls for energy over calm. For accessible text, use it on black or near-black backgrounds (5.83:1, passes WCAG AA) rather than white.

Where Fire Opal works
- Web & UI: Best as a button fill, badge, or accent — pair it with white text only at large sizes, and check contrast.
- Interiors: Strong for a whole room, excellent in doses: an accent wall, cabinetry, or a statement chair.
- Fashion: Wears best as the statement piece — a top, scarf, or shoes — against neutral basics.
- Branding: High-energy brand material: strong for food, fitness, and youth-facing marks — use sparingly in UI.
- Web & UI: A supporting-cast color for UI: chart fills, tags, empty-state illustrations — not text.
- Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
