#373e41 - Mine Shaft color

A deep, muted charcoal with cool slate undertones leaning toward green-blue. It reads as an urban stone tone—subtle, restrained, and sophisticated—ideal for backgrounds, UI elements, or modern interiors that require quiet depth. It pairs well with warm ochres, soft creams, and brass accents to add contrast, or with lighter grays and icy blues for a monochromatic, moody palette. The color evokes evening fog, worn metal, and industrial minimalism without feeling harsh.
