Blue Whale
Also known as: Into the Night, Tangaroa, Petrol Slumber, Tahitian Pearl
As a deep take on blue, Blue Whale carries cool and professional energy that suits trust-driven interfaces and corporate branding. Match it with brown accents when the design calls for energy over calm. On white it reads clearly at 12.92:1 contrast — safe for body text under WCAG AA.

Where Blue Whale 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, empty-state illustrations — not text.
- Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
