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