Cape Verde

Also known as: Castleton Green, Plankton Green, Myrtle Deep Green, Baltic Prince

Cape Verde sits on the cool side of the spectrum: a vivid cyan that feels crisp and refreshing. Try it in tech interfaces and water themes. Match it with red accents when the design calls for energy over calm. It's dark enough to use for text on white backgrounds (8.70:1, passes WCAG AA).

Where Cape Verde 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.
