The hex color #0D4B98, also known as Congress Blue, presents some accessibility considerations, especially for web content. Its relatively low lightness value (approximately 11%) means that it requires careful attention to contrast ratios to ensure readability and usability. When used as a background color, it's essential to pair it with a light-colored text to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to comply with Level AA requirements. For Level AAA compliance, even higher contrast ratios are needed. Tools like contrast checkers can help web developers verify compliance. Avoid using this color for essential visual information without sufficient contrast. Consider providing alternative color schemes to accommodate users with visual impairments. When using this color for links, ensure that the links are visually distinct from surrounding text, for instance, by adding an underline or a different font weight.
