- Pair Admiral Blue with white text for the strongest reading experience: that combination gives 10.9:1.
- Used as a text colour on white, it clears the 3:1 bar for large headings.
- Never rely on Admiral 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 Admiral Blue, add a solid overlay first. Contrast measured against a flat colour does not hold over varying imagery.

Design recommendations
- Build lighter and darker variants by changing only the lightness in
hsl(210, 71%, 25%). Keeping hue fixed is what makes a scale look intentional. - Give Admiral 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.
