18.69:1 — AAA for normal textAccessibility notes
- Pair Ink Blue with white text for the strongest reading experience: that combination gives 18.69:1.
- Used as a text colour on white, it clears the 3:1 bar for large headings.
- Never rely on Ink 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 Ink 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(226, 60%, 10%). Keeping hue fixed is what makes a scale look intentional. - Give Ink 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.
