- Used as a text colour on white, it clears the 3:1 bar for large headings.
- Never rely on Regatta Blue alone to communicate state. Add an icon, label or underline so the meaning survives for colour-blind users and in greyscale printing.

hsl(212, 67%, 32%). Keeping hue fixed is what makes a scale look intentional. - Give Regatta 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.
