Accessibility notes

  • Pair Imperial Blue with white text for the strongest reading experience: that combination gives 12.54:1.
  • Used as a text colour on white, it clears the 3:1 bar for large headings.
  • Never rely on Imperial 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 Imperial Blue, add a solid overlay first. Contrast measured against a flat colour does not hold over varying imagery.

Common uses

  • Page and section backgrounds in dark interfaces, where it holds white text cleanly.
  • 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 100%, 77%, 0%, 42%.
  • 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(226, 100%, 29%). Keeping hue fixed is what makes a scale look intentional.
  • Give Imperial 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.
