#3c464b - Nightshade color

This deep, muted blue-gray leans toward a smoky teal with cool green undertones. It reads as a sophisticated slate—subdued, modern, and slightly atmospheric—evoking stormy coastal waters, aged metal, or weathered concrete. Use it for backgrounds, navigation bars, or accents when you want a calming, grounded presence that still feels contemporary. It pairs well with warm copper, soft beige, or crisp white to add contrast, or with paler blues and greens for a monochromatic, layered look.
