Bellflower
Also known as: Evening Lagoon , Blue Iris , Submarine Base , Iris Bloom
Quietly calm and trustworthy, Bellflower is a cool-toned blue that earns its keep in finance apps and trust-driven interfaces. Its complement lands in brown territory, which makes for striking two-color pairings. It's dark enough to use for text on white backgrounds (5.32:1, passes WCAG AA).

Where Bellflower works
- Web & UI: Dark enough for body text and icons on white backgrounds. It passes WCAG AA as-is.
- Interiors: Soft and low-saturation: a candidate for full walls, where vivid colors overwhelm.
- 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.
- Interiors: Strong for a whole room, excellent in doses: an accent wall, cabinetry, or a statement chair.
