Sensible jobs for this swatch

supporting UI accents
text or icons on a white canvas

On a black or near-black UI, #676364 is 3.55:1. Prefer it as a fill, border, or large heading rather than 16px copy.

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.
