Where Mario 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 — front door, built-ins, or one bold wall.
  • Fashion: One garment in this color carries an outfit; two starts to compete.
  • Branding: Commands attention in logos and packaging; balance it with generous neutral space.
  • Web & UI: Reads as an interactive accent: fills, hovers, focus rings. Keep body text in a darker neutral.
  • Branding: Best in a brand's supporting palette — packaging interiors, patterns, campaign accents.
