Dark Knight
Also known as: Liberty Blue , Sambucus , Lost in Sadness , Nightwalker
On screen, Dark Knight registers as calm and trustworthy: a deep blue at home in finance apps and trust-driven interfaces. Set it against a black accent when you want the combination to pop. It's dark enough to use for text on white backgrounds (17.28:1, passes WCAG AA).
