#0B5989 Hex Color
Deep, dim blue with steady footing
Somewhere between deep ocean water and a navy work uniform, #0b5989 is a dark, dim blue with a cool cast and low saturation. That restraint suits banking dashboards, dark mode UIs, and nautical branding where flash would feel wrong. White text clears WCAG AA against it at roughly 7.5:1 contrast, so it holds up as a dominant base. It looks richer beside warm coral or terracotta accents than beside plain gray.
