A muted, mid-tone gray-green with subtle brown undertones, evoking stone and weathered olive.

In bright light it leans cooler and slate-like; under warm illumination it reveals olive and taupe hints. Versatile and sophisticated, it suits rustic, modern, and vintage palettes, pairing beautifully with cream, rust, amber, deep navy, and natural wood for cozy, understated elegance.
