The hex color #0B4885, also known as Congress Blue, presents some accessibility considerations for web development. When used as a background color, it requires careful selection of foreground text color 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. Lighter shades of yellow, beige, or white would generally work well as foreground colors. Tools like contrast checkers can assist in verifying compliance. It's important to avoid using this color for interactive elements or links without proper visual cues, like underlines or borders, as color alone should not be the only method to convey information. Proper semantic HTML and ARIA attributes can further enhance the accessibility of content using this color. Consideration should be given to users with color vision deficiencies, where the use of this color should be complemented by other visual indicators.
