The color #004E98, also known as Congress Blue, presents some accessibility challenges. Its low lightness value means it has a dark appearance. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Using dark or mid-toned text on a #004E98 background would likely fail accessibility checks, making the text difficult to read for users with visual impairments. Conversely, as a text color, it is best used on a very light or white background. It's essential to test color combinations with accessibility tools to ensure compliance and provide an inclusive user experience. When using this color for interactive elements, such as buttons or links, ensure sufficient visual cues beyond color alone are present to aid users who may have difficulty distinguishing colors.
