Where Sulphuric works

  • Web & UI: Best as a button fill, badge, or accent — pair it with white text only at large sizes, and check contrast.
  • 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: High-energy brand material: strong for food, fitness, and youth-facing marks — use sparingly in UI.
  • Web & UI: A supporting-cast color for UI: chart fills, tags, empty-state illustrations — not text.
  • Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
