Practical advice

Accessibility and inclusion
Red is one of the two colors most affected by color vision deficiency. Never rely on red alone to convey meaning — always pair it with an icon, text label or pattern. Also remember that red text on white backgrounds rarely passes WCAG AA at typical sizes; use darker reds or a dark background for readable red text.
  • Use a deeper red (#991B1B or darker) for text on white.
  • Pair red with neutral surfaces so it stays urgent without overwhelming.
  • Use it sparingly — red loses impact when used everywhere.
  • Always add an icon or text label to reinforce meaning.

Examples in known brands

Red is one of the most-used brand colors. Common examples include: Netflix, YouTube, Coca-Cola, Marvel, Ferrari, Target, Vodafone, Adobe. Each uses a different red — from warm crimson to deep burgundy — which is part of how the brands feel distinct despite sharing the same hue family.
