Sensible jobs for this swatch

supporting UI accents
text or icons on charcoal / dark mode

Do not use #b4b4b7 as small body text on white — 2.07:1 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: Neutrality, balance, and modernity. Essential for UI chrome, typography, and systems. Common uses still include buttons, charts, and accents in the Grey range — always verify the pair for this exact hex in the contrast checker.
