Color palette

Color reinforces brand recognition. Use your brand colors strategically in email signatures without overwhelming the design.

Color Guidelines

  • Limit colors: 2-3 maximum (plus black/gray for text)
  • Primary brand color: Use for name or accent elements
  • Secondary color: Use sparingly for links or highlights
  • Text color: Keep main text black or dark gray

Where to Use Color

  • Your name (bold in brand color)
  • Links (consistent link color)
  • Divider lines
  • Social icons
  • CTA buttons

Contrast Matters

Ensure text is readable against any background. Test your signature in both light and dark mode email clients.

Using Hex Codes

Always use exact hex color codes for consistency:

color: #6366f1; /* Exact brand violet */

Common Mistakes

  • Too many colors (looks chaotic)
  • Light text on white (hard to read)
  • Inconsistent colors across team
  • Using colors that don't match brand

On-brand colors every time

Siggly locks in your brand colors so every signature matches perfectly.
