Where Fly-by-Night works

  • Web & UI: Use it directly for text on light surfaces; it clears AA contrast without adjustment.
  • Interiors: Use it where you want the eye to land: a front door, built-ins, or one bold wall.
  • Fashion: One garment in this color carries an outfit; two starts to compete.
  • Branding: The safest brand-primary family there is; differentiate with an unexpected accent.
  • Web & UI: Use it decoratively for dividers, chart series, and illustration accents, and let neutrals carry the type.
  • Branding: Best in a brand's supporting palette: packaging interiors, patterns, campaign accents.
