Where Stone Cold 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 — 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 — dividers, chart series, illustration accents — and let neutrals carry the type.
- Fashion: One garment in this color carries an outfit; two starts to compete.
