Accessibility notes

  • Pair Yale Blue with white text for the strongest reading experience: that combination gives 8.41:1.
  • Used as a text colour on white, it clears the 3:1 bar for large headings.
  • Never rely on Yale Blue alone to communicate state. Add an icon, label or underline so the meaning survives for colour-blind users and in greyscale printing.
  • When placing text over a photograph tinted with Yale Blue, add a solid overlay first. Contrast measured against a flat colour does not hold over varying imagery.

Using Yale Blue in CSS and HTML

}

</div>

Common uses

  • Primary buttons, active navigation states and chart series.
  • Royal Navy palettes for brand systems that need a dependable cool anchor.
  • Print work where a deep blue is preferred to black, using the CMYK build 90%, 47%, 0%, 43%.
  • Data visualisation, as one step in a lightness-based navy scale.

Design recommendations

  • Build lighter and darker variants by changing only the lightness in hsl(212, 81%, 32%). Keeping hue fixed is what makes a scale look intentional.
  • Give Yale Blue at least one warm counterweight. A cool palette with no warm accent tends to read as cold rather than calm.
  • Saturation is high here, so use it in measured amounts. Large flat areas of a saturated navy can feel heavy on screen.
