Usage Guidelines

Do

  • Use dark text (--color-text-primary) for headings
  • Use Deep Space Blue only for links and interactive elements
  • Use Princeton Orange for tagline, CTAs, and hover states
  • Use Source Serif 4 for all headings and display text
  • Use Inter for all body and UI text
  • Maintain minimum clear space around logo equal to mark height
  • Use reversed (white) logo on dark backgrounds

Don't

  • Color headings or category titles with blue
  • Use Flag Red except for Climate Global timeline entry
  • Add fade-in or scroll-triggered animations
  • Introduce fonts beyond Source Serif 4 and Inter
  • Stretch or distort the logo
  • Use drop shadows or effects on the logo
  • Place logo on busy backgrounds without contrast
