Castaway

Also known as: Aqua Sky, Maritime Soft Blue, Azul Turquesa, Dickie Bird

Part of the cyan family, Castaway pairs a medium base with a crisp and refreshing presence — ideal for tech interfaces and water themes. Because it leans cool, balancing it with a red keeps a palette from feeling one-note. Against dark backgrounds it stays legible (9.43:1), but avoid it as text on white.

Where Castaway works

  • Web & UI: A supporting-cast color for UI: chart fills, tags, empty-state illustrations — not text.
  • Interiors: Strong for a whole room, excellent in doses: an accent wall, cabinetry, or a statement chair.
  • Fashion: Wears best as the statement piece — a top, scarf, or shoes — against neutral basics.
  • Branding: Sits in the trust register — a natural primary for finance, health, and B2B brands.
  • Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
