Oil
Also known as: Charcoal , Phantom Ship , Wet Concrete , Dryad Bark
As a deep take on gray, Oil carries neutral and understated energy that suits minimal interfaces and architecture. Its complement lands in gray territory, which makes for striking two-color pairings. It's dark enough to use for text on white backgrounds (12.75:1, passes WCAG AA).

Where Oil 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, and empty-state illustrations, but not text.
- Fashion: Wears best as the statement piece, a top, scarf, or shoes, against neutral basics.
