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: a 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 for dividers, chart series, and illustration accents, and let neutrals carry the type.
- Branding: Best in a brand's supporting palette: packaging interiors, patterns, campaign accents.
