The color #234C78, also known as Chathams Blue, presents some accessibility challenges, particularly when used as a background color for text. Its relatively low luminance (brightness) means that it requires careful consideration of the foreground text color to ensure sufficient contrast. According to WCAG (Web Content Accessibility Guidelines) 2.0, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. For users with low vision or color blindness, inadequate contrast can make text difficult or impossible to read. It's recommended to test color combinations using accessibility tools to verify compliance. As an alternative, consider using a lighter shade of blue or a contrasting color like white or yellow for text to improve readability and meet accessibility standards. Ensure interactive elements such as buttons and links have sufficient visual cues to be easily identified.
