The color #0B408D, also known as Congress Blue, presents some accessibility challenges, especially when used as text on a white background. Its low lightness value (around 15%) means that it lacks sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Congress Blue typically falls short of these ratios on light backgrounds, making it difficult for users with visual impairments to read. To improve accessibility, consider using Congress Blue with lighter shades for the background color, or use it as a background with white or very light-colored text. Alternatively, you can use color contrast tools to find accessible color combinations. Utilizing Congress Blue for graphical elements such as icons or large shapes may pose fewer accessibility concerns since the contrast requirements are less stringent.
