Hydro

Also known as: Flip, Wild River, Silken Peacock, Winter Storm

Quietly clean and modern, Hydro is a cool-toned cyan that earns its keep in healthcare apps and modern branding. Because it leans cool, balancing it with a brown keeps a palette from feeling one-note. It's dark enough to use for text on white backgrounds (5.14:1, passes WCAG AA).

Where Hydro 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: One garment in this color carries an outfit; two starts to compete.
  • 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.
  • Branding: Best in a brand's supporting palette — packaging interiors, patterns, campaign accents.
