Does #0017b2 work well for dark mode interfaces?
This shade is generally too dark and vivid for dark mode UI backgrounds, as it lacks sufficient contrast against standard white or light gray text. It is far more effective in light-themed designs where its deep, authoritative energy stands out against clean, neutral spaces.
Is #0017b2 readable on white or black?
#0017b2 has a 11.89:1 contrast ratio on white and 1.76:1 on black. WCAG asks for 4.5:1 for body text and 3:1 for large text, so on white it works for body text and on black it is too faint for text. Try other pairs in the contrast checker.
