The color #123B86, also known as Congress Blue, presents some accessibility challenges, primarily due to its dark hue. When used as a background color, it necessitates very light text to ensure sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using lighter shades of blue or other contrasting colors for interactive elements can improve usability. Testing the color combination with accessibility tools like WebAIM's Contrast Checker is crucial to verify compliance with accessibility standards and ensure a positive user experience for everyone, including those with disabilities. Consideration should also be given to users with cognitive impairments, ensuring that color alone is not used as the sole means of conveying information.
