The color #004498, also known as Congress Blue, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it requires light-colored text (white or very pale shades) to ensure sufficient contrast for readability, ideally meeting WCAG AA standards. Using dark text on this background would likely fail accessibility tests. As a text color itself, #004498 needs to be paired with a very light background. The specific contrast ratio should be checked with an accessibility tool to confirm compliance. Consideration should also be given to users with visual impairments, who may struggle to distinguish between shades that are too similar. When used for interactive elements, provide clear visual cues beyond color alone, such as underlines for links or icons for buttons, to make the interface more usable for everyone.
