Thalassa
Also known as: Aqueduct , Glassmith , Spearfish , Adonis
Thalassa is a medium, gentle cyan that reads as crisp and refreshing. It earns its place in modern branding and tech interfaces. Reach for a pink companion shade to give Thalassa maximum contrast. Against dark backgrounds it stays legible (8.37:1), but avoid it as text on white.

Where Thalassa 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.
