The hex color #0a2439, also known as Firefly, presents some accessibility challenges, especially concerning text legibility. Due to its dark nature, it necessitates the use of very light or white text to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to comply with WCAG (Web Content Accessibility Guidelines) standards. Using contrast checking tools is highly advisable during development to ensure compliance. Furthermore, consider users with low vision or color blindness, who may struggle to differentiate elements if the color is used for critical information or interactive elements. Providing supplementary cues, such as icons or text labels, can significantly improve the usability for a broader audience. Ensure that interactive elements using this color also have sufficient focus indicators for keyboard navigation.
