The hex color #123D86, also known as Congress Blue, presents some accessibility considerations for web developers. Its relatively low luminance can pose challenges when used as text against a white or very light background, potentially failing WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended for Level AA compliance. For enhanced accessibility (Level AAA), these ratios increase to 7:1 and 4.5:1, respectively. Using a color contrast checker is essential to verify compliance. If #123D86 is used for text, pairing it with a very light or white background should be avoided. Lighter shades of yellow, orange, or even light gray or white backgrounds would offer better contrast and improve readability for users with visual impairments. Alternatively, consider using #123D86 for graphical elements where the contrast requirements are less stringent, or ensure the text size is sufficiently large to meet the reduced contrast ratio requirements for large text.
