Cathedral
Also known as: Cathedral Grey, Actor’s Star, Ellie Grey, Silver Grey
Part of the gray family, Cathedral pairs a soft base with a balanced and versatile presence — ideal for neutral backgrounds and minimal interfaces. Because it leans neutral, balancing it with a gray keeps a palette from feeling one-note. For accessible text, use it on black or near-black backgrounds (9.06:1, passes WCAG AA) rather than white.

Where Cathedral 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.
