Vitamin C

Also known as: Zambia, Hephaestus Gold, Jack-O, Aromango

Vitamin C is what happens when orange turns medium and vivid. The effect is friendly and enthusiastic, made for autumn palettes and friendly UI accents. Because it leans warm, balancing it with a blue keeps a palette from feeling one-note. Accessibility-wise, it needs a dark backdrop — 9.81:1 on black clears AA.

Where Vitamin C 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.
