Black Olive
Also known as: Zeus, Rosin, Black Powder, Andiron
Black Olive is a rich, muted gray that reads as neutral and understated. It shines in minimal interfaces and architecture. Set it against a gray accent when you want the combination to pop. On white it reads clearly at 11.14:1 contrast — safe for body text under WCAG AA.

Where Black Olive 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.
