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
