Seafarer
Also known as: Kinetic Blue , Victorian Peacock , Shimmering Sea , Swallow Blue
Quietly calm and trustworthy, Seafarer is a cool-toned blue that earns its keep in trust-driven interfaces and corporate branding. Set it against a brown accent when you want the combination to pop. On white it reads clearly at 9.04:1 contrast, safe for body text under WCAG AA.

Where Seafarer works
- Web & UI: Dark enough for body text and icons on white backgrounds. It passes WCAG AA as-is.
- 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.
- Web & UI: A supporting-cast color for UI: chart fills, tags, and empty-state illustrations, but not text.
- Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
