Sensible jobs for this swatch

supporting UI accents
large titles on light backgrounds (WCAG AA Large)
text or icons on charcoal / dark mode

Do not use #777b89 as small body text on white — 4.22:1 misses WCAG AA (4.5:1). Pair it with a darker shade from the scale below, or check pairs in the contrast checker.

Low saturation makes this easy to overuse as a neutral. Keep one chromatic accent elsewhere so the interface does not go muddy.

Family context: Calm professionalism with cool neutrality. Excellent for dashboards and docs. Common uses still include buttons, charts, and accents in the Blue Grey range — always verify the pair for this exact hex in the contrast checker.
