Aquarius
Also known as: River Blue , Summer Air , Ocean Sigh , Santorini
Quietly clean and modern, Aquarius is a cool-toned cyan that earns its keep in tech interfaces and water themes. A orange counterpart from the complementary harmony gives it the most tension. Accessibility-wise, it needs a dark backdrop: 8.21:1 on black clears AA.

Where Aquarius works
- Web & UI: Best as a button fill, badge, or accent. Pair it with white text only at large sizes, and check contrast.
- 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.
