The color #0A4B91, also known as Congress Blue, presents some accessibility challenges, primarily due to its relatively low luminance. When used as a background color, it requires careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. White (#FFFFFF) or very light shades of gray are generally good choices for text on a #0A4B91 background. Conversely, using dark text colors such as black (#000000) would create insufficient contrast and make the content difficult to read for users, especially those with visual impairments. Tools like WebAIM's Contrast Checker can be used to accurately assess the contrast ratio between different color combinations. When using Congress Blue, consider providing alternative color schemes for users who require higher contrast, enhancing the overall user experience for everyone.
