Thunderbird

Also known as: Red Chilli, Decadent Red, Redbox, Gatsby Brick

With its warm undertone, Thunderbird (#923830) comes across as confident and commanding. Designers reach for it in call-to-action buttons and food branding. Match it with cyan accents when the design calls for energy over calm. It's dark enough to use for text on white backgrounds (7.42:1, passes WCAG AA).

Where Thunderbird works

  • Web & UI: Dark enough for body text and icons on white backgrounds — it passes WCAG AA as-is.
  • 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.
