The color #043F97, also known as Congress Blue, presents significant accessibility challenges due to its dark hue. When used as a background color, it necessitates very light text to ensure sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Congress Blue may struggle to meet these ratios with moderately light colors. Therefore, careful consideration is needed when pairing it with text or other interactive elements. It's crucial to test color combinations with accessibility tools to verify compliance and ensure that all users can perceive the content effectively. Using a lighter shade of blue or a completely different color palette might be necessary to achieve optimal accessibility.
