Red Stop

#FF2222

Also known as: Traffic Red , Superman Red , British Phone Booth , Little Ladybug

As a medium take on red, Red Stop carries passionate and urgent energy that suits food branding and sale banners. A cyan counterpart from the complementary harmony gives it the most tension. Accessibility-wise, it needs a dark backdrop: 5.50:1 on black clears AA.

Where Red Stop 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, and empty-state illustrations, but not text.
  • Branding: A secondary brand color by nature: it supports a stronger primary and shines in illustration.
