Dark Blue
Also known as: Matisse , Tidal Wave , Venice Blue , Bluey
As a rich take on blue, Dark Blue carries calm and trustworthy energy that suits finance apps and trust-driven interfaces. Set it against a brown accent when you want the combination to pop. It's dark enough to use for text on white backgrounds (7.18:1, passes WCAG AA).

Where Dark Blue 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: a front door, built-ins, or one bold wall.
- Fashion: One garment in this color carries an outfit; two starts to compete.
- Branding: The safest brand-primary family there is; differentiate with an unexpected accent.
- Web & UI: Use it decoratively for dividers, chart series, and illustration accents, and let neutrals carry the type.
- Branding: Best in a brand's supporting palette: packaging interiors, patterns, campaign accents.
