Vulcan
Also known as: Hawk’s Eye, Artist’s Charcoal, Metalise, Tribecca Corner
Vulcan sits on the neutral side of the spectrum: a muted gray that feels balanced and versatile. Try it in neutral backgrounds and minimal interfaces. Because it leans neutral, balancing it with a gray keeps a palette from feeling one-note. Accessibility-wise, it clears AA for text on white at 11.75:1.

Where Vulcan works
- Web & UI: Dark enough for body text and icons on white backgrounds — it passes WCAG AA as-is.
- Interiors: Strong for a whole room, excellent in doses: an accent wall, cabinetry, or a statement chair.
- Fashion: A wardrobe neutral: it anchors outfits and pairs with nearly any accent color.
- Branding: Craft and heritage material — coffee, leather goods, and premium packaging live here.
- Web & UI: A supporting-cast color for UI: chart fills, tags, empty-state illustrations — not text.
- Fashion: Wears best as the statement piece — a top, scarf, or shoes — against neutral basics.
