Blue Blood
Also known as: Stormy Sea, AuroMetalSaurus, Rock Creek, Coney Island
A muted gray with a balanced and versatile character, Blue Blood works beautifully 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 — dividers, chart series, illustration accents — and let neutrals carry the type.
- 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.
- 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.
