Blue Moon
Also known as: Winter Time, Enchanted Well, Cape Pond, Alpine Lake
Part of the cyan family, Blue Moon pairs a medium base with a clean and modern presence — ideal for water themes and healthcare apps. Blue Moon plays well with brown tones — the harmonies below show exactly which ones. For accessible text, use it on black or near-black backgrounds (5.85:1, passes WCAG AA) rather than white.

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