The hex color #0A4C91, also known as Congress Blue, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it requires light-colored text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Given the darkness of #0A4C91, lighter shades of white, yellow, or light gray are advisable for text. Using contrast checking tools is highly recommended to verify compliance with accessibility standards. Additionally, avoid using this color for critical information if color is the sole means of conveying it, as colorblind users may struggle to differentiate it from similar dark shades. Consider providing alternative visual cues, such as icons or text labels, to enhance accessibility for all users. Proper attention to these details ensures a more inclusive and user-friendly design.
