The hex color #0a47aa, a shade of cobalt, presents specific accessibility considerations for web developers. Its relatively low luminance necessitates careful attention to color contrast ratios, particularly when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background. Developers should use contrast checking tools to ensure compliance.
