The hex color #004080, also known as Congress Blue, presents some accessibility considerations for web developers. Its relatively low lightness value means that it requires careful attention to contrast ratios, especially when used for text or interactive elements. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. To ensure accessibility, aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text against its background. Using tools to measure contrast ratios is highly recommended during the design process. Consider pairing Congress Blue with lighter shades of gray, yellow, or white to meet these contrast requirements. Avoid using it with darker colors, as this can make content difficult to read. When used for links or buttons, provide additional visual cues like underlines or icons to enhance discoverability for all users. Remember to test your color choices with assistive technologies to ensure compatibility and usability.
