Onyx
Also known as: Ravenwood, Medium Black, Machine Gun Metal, Wood Charcoal
Onyx is what happens when gray turns rich and muted. The effect is balanced and versatile, made for minimal interfaces and architecture. Match it with gray accents when the design calls for energy over calm. Accessibility-wise, it clears AA for text on white at 9.57:1.

Where Onyx 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.
