Eclipse
Also known as: After Dark , Binrouji Black , Pitch , Brownish Black
Few grays feel this muted. Eclipse leans neutral and balanced and versatile, which points it toward architecture and editorial layouts. For contrast, pair it with a gray from its complementary palette below. On white it reads clearly at 11.32:1 contrast, safe for body text under WCAG AA.

RAL values are widely published approximations of the physical standard. For Pantone-adjacent workflows, match by eye against a physical fan deck. Pantone's values are proprietary and device-dependent, so we don't print lookups.
Where Eclipse works
- Web & UI: Use it directly for text on light surfaces; it clears AA contrast without adjustment.
- Interiors: Use it where you want the eye to land: a front door, built-ins, or one bold wall.
- Fashion: Works as a base layer or outerwear tone that lets brighter pieces do the talking.
- Branding: As a brand anchor it reads established and tactile; pair with a single vivid accent for energy.
- Web & UI: Use it decoratively for dividers, chart series, and illustration accents, and let neutrals carry the type.
- Fashion: One garment in this color carries an outfit; two starts to compete.
