Where Marine 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.
