The hex color #11388A, also known as Congress Blue, presents several accessibility considerations for web developers. Its dark hue results in a low luminance value, which means that sufficient contrast with foreground elements is crucial. When using this color as a background, ensure that text or interactive elements placed on top have a high 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. Utilizing tools like contrast checkers can help verify compliance. Additionally, avoid using #11388A as the sole indicator for interactive elements; provide supplementary cues like underlines or icons to ensure usability for users with visual impairments or color blindness. Careful consideration of these factors will enhance the overall accessibility of your website or application.
