Sensible jobs for this swatch

supporting UI accents
text or icons on a white canvas

On a black or near-black UI, #3c4142 is 2.03:1. 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: 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.
