Accessibility notes

  • Pair Graphite Blue with white text for the strongest reading experience: that combination gives 11.65:1.
  • Used as a text colour on white, it clears the 3:1 bar for large headings.
  • Never rely on Graphite 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 Graphite Blue, add a solid overlay first. Contrast measured against a flat colour does not hold over varying imagery.

}

</div>

Common uses

  • Page and section backgrounds in dark interfaces, where it holds white text cleanly.
  • Slate 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 38%, 18%, 0%, 72%.
  • 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(209, 23%, 23%). Keeping hue fixed is what makes a scale look intentional.
  • Give Graphite Blue at least one warm counterweight. A cool palette with no warm accent tends to read as cold rather than calm.
  • Saturation is moderate, which makes this shade forgiving across large areas and long reading sessions.
