Koi

Also known as: Fresh Acorn, Vermilion Waxcap, Tangerine Bliss, Casa de Oro

Quietly playful and vibrant, Koi is a warm-toned orange that earns its keep in friendly UI accents and children's products. Set it against a cyan accent when you want the combination to pop. For accessible text, use it on black or near-black backgrounds (5.70:1, passes WCAG AA) rather than white.

Where Koi works

  • Web & UI: Reads as an interactive accent: fills, hovers, focus rings. Keep body text in a darker neutral.
  • Interiors: Use it where you want the eye to land — front door, built-ins, or one bold wall.
  • Fashion: One garment in this color carries an outfit; two starts to compete.
  • Branding: Commands attention in logos and packaging; balance it with generous neutral space.
  • Web & UI: Use it decoratively — dividers, chart series, illustration accents — and let neutrals carry the type.
  • Branding: Best in a brand's supporting palette — packaging interiors, patterns, campaign accents.
