Horizon
Also known as: Relaxed Blue , Bell Blue , Spirit Mountain , Gothic
Few cyans feel this gentle. Horizon leans cool and crisp and refreshing, which points it toward tech interfaces and water themes. A brown counterpart from the complementary harmony gives it the most tension. For accessible text, use it on black or near-black backgrounds (5.49:1, passes WCAG AA) rather than white.

Where Horizon works
- Web & UI: A supporting-cast color for UI: chart fills, tags, and empty-state illustrations, but not text.
- Interiors: Strong for a whole room, excellent in doses: an accent wall, cabinetry, or a statement chair.
- Fashion: A wardrobe neutral: it anchors outfits and pairs with nearly any accent color.
- Branding: Sits in the trust register: a natural primary for finance, health, and B2B brands.
- Fashion: Wears best as the statement piece, a top, scarf, or shoes, against neutral basics.
- Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
