#3e3f41 - Dark Engine color

This deep, muted charcoal leans toward cool slate rather than warm graphite. It reads as a dark gray with subtle blue-green undertones, giving it a slightly smoky, industrial character. The color feels sophisticated, restrained, and modern—excellent for backgrounds, UI surfaces, or typography when paired with lighter neutrals. It provides a calm, professional atmosphere and contrasts nicely with warm accents or pale pastels. In lighting, it can appear nearly black or reveal its cool, stone-like nuance.
