Wolfram
Also known as: Brainstem Grey, Fortress Grey, Covered in Platinum, Tangled Web
As a soft take on gray, Wolfram carries neutral and understated energy that suits neutral backgrounds and minimal interfaces. Wolfram plays well with gray tones — the harmonies below show exactly which ones. For accessible text, use it on black or near-black backgrounds (10.34:1, passes WCAG AA) rather than white.

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 Wolfram works
- Web & UI: Use it decoratively — dividers, chart series, illustration accents — and let neutrals carry the type.
- Interiors: Muted enough to paint all four walls; sample it in both daylight and evening light before committing.
- 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.
- Interiors: Use it where you want the eye to land — front door, built-ins, or one bold wall.
- Fashion: One garment in this color carries an outfit; two starts to compete.
