The hex color #0A4A88, also known as Congress Blue, presents some accessibility considerations, particularly in web design. Its relatively dark hue means that careful attention must be paid to color contrast. When used as a background color, it's crucial to ensure that any text or interactive elements layered on top have sufficient luminance contrast ratio, ideally meeting WCAG (Web Content Accessibility Guidelines) AA or AAA standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended to ensure readability for users with visual impairments. When #0A4A88 is used for text, a lighter background color is required to meet accessibility standards. Using color contrast analysis tools during the design process is essential to verify compliance and provide an inclusive experience for all users, including those with low vision or color blindness. It's also good to provide alternate ways to convey the information that isn't only by the color alone.
