The hex color #103D88, also known as Congress Blue, presents some accessibility considerations for web design. Its relatively dark nature means that 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 normal text and 3:1 for large text. White or very light shades of yellow and green would likely provide adequate contrast, promoting readability for users with visual impairments. Designers should utilize contrast checking tools to confirm compliance with accessibility standards. Moreover, avoid using this color as the sole indicator of interactive elements, as colorblind users may not be able to distinguish it effectively. Consider using supplementary cues such as underlines, icons, or bold text to enhance usability for all users.
