The color #0D398E, also known as Congress Blue, presents some accessibility challenges, particularly in text-based applications. Due to its relatively low lightness value, it can be difficult to achieve sufficient contrast with lighter background colors, such as white or pale yellow. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) AA standards. Using #0D398E for text on a light background might not meet these ratios, potentially making the content hard to read for individuals with visual impairments. To improve accessibility, consider using a lighter shade of blue or pairing it with a very light or contrasting color for text or interactive elements. Always test the color combination with accessibility tools to ensure compliance with accessibility standards and optimal readability.
