The hex color #0F398C, also known as Congress Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text to ensure sufficient contrast for readability, ideally adhering to WCAG (Web Content Accessibility Guidelines) AA or AAA standards. Using darker text on this background would likely fail contrast checks, making it difficult for users with visual impairments to read the content. Therefore, designers should use tools to check the contrast ratio. Also, avoid using this color as the sole indicator for interactive elements, like links, as colorblind users might miss them. Providing alternative cues, such as underlines or icons, is crucial for inclusive design.
