Where Bluebonnet works

  • Web & UI: Dark enough for body text and icons on white backgrounds — it passes WCAG AA as-is.
  • 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: Best as a button fill, badge, or accent — pair it with white text only at large sizes, and check contrast.
  • Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
