Blue Blood
Also known as: Stormy Sea , AuroMetalSaurus , Rock Creek , Coney Island
Blue Blood is what happens when gray turns medium and muted. The effect is balanced and versatile, made for architecture and editorial layouts. Its complement lands in gray territory, which makes for striking two-color pairings. For accessible text, use it on black or near-black backgrounds (4.98:1, passes WCAG AA) rather than white.

Where Blue Blood works
- Web & UI: Use it decoratively for dividers, chart series, and illustration accents, and let neutrals carry the type.
- 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.
- Fashion: One garment in this color carries an outfit; two starts to compete.
- Branding: Best in a brand's supporting palette: packaging interiors, patterns, campaign accents.
