Where Poisonous works

  • Web & UI: Reads as an interactive accent: fills, hovers, focus rings. Keep body text in a darker neutral.
  • 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: A brand green signals freshness; deepen it for finance, brighten it for eco-consumer products.
  • Web & UI: Use it decoratively — dividers, chart series, illustration accents — and let neutrals carry the type.
  • Branding: Best in a brand's supporting palette — packaging interiors, patterns, campaign accents.
