The color #004085, also known as Congress Blue, presents some accessibility challenges, especially regarding color contrast. When using this color for text or interactive elements, it's crucial to ensure sufficient contrast against the background. According to WCAG guidelines, the minimum contrast ratio for normal text is 4.5:1, and for large text (14pt bold or 18pt regular) it's 3:1. Congress Blue is a dark color, so it will generally require light backgrounds to meet these ratios. Tools such as WebAIM's contrast checker can be used to test contrast ratios. If sufficient contrast cannot be achieved with the desired background, consider using a lighter shade of blue or an entirely different color that provides better contrast. Also, it is important to test how the color appears to users with color vision deficiencies, and provide alternative cues (e.g., underlines, icons) to ensure important information is conveyed effectively. Properly implemented, Congress Blue can be accessible with careful consideration of contrast and alternative cues.
