Abyssal

Also known as: Dutch Licorice, Club Navy, Dark Night, Pacific Spirit

Quietly calm and trustworthy, Abyssal is a cool-toned blue that earns its keep in finance apps and trust-driven interfaces. A brown counterpart from the complementary harmony gives it the most tension. It's dark enough to use for text on white backgrounds (8.79:1, passes WCAG AA).

Where Abyssal works

  • Web & UI: Use it directly for text on light surfaces; it clears AA contrast without adjustment.
  • Interiors: Use it where you want the eye to land — front door, built-ins, or one bold wall.
  • Fashion: Works as a base layer or outerwear tone that lets brighter pieces do the talking.
  • Branding: The safest brand-primary family there is; differentiate with an unexpected accent.
  • Web & UI: Use it decoratively — dividers, chart series, illustration accents — and let neutrals carry the type.
  • Fashion: One garment in this color carries an outfit; two starts to compete.
