The hex color #0B4E90, also known as Congress Blue, presents certain accessibility considerations for web developers. Its relatively dark hue means that it requires careful selection of foreground text and other visual elements to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #0B4E90 as a background, lighter colors such as white (#FFFFFF) or light yellows and greens are advisable for text to meet these contrast requirements. Testing with accessibility tools is crucial to confirm compliance and avoid potential barriers for users with visual impairments. When this color is used for interactive elements like buttons and links, hover, focus, and active states must also be designed with adequate contrast to provide clear visual feedback to the user. This color should never be the only means of conveying information.
