The color #123F86, also known as Congress Blue, presents some accessibility challenges, especially concerning text contrast. When used as a background color, it necessitates light-colored text (white or a very light tint) to ensure readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color may not be suitable for conveying critical information alone, such as in alerts or warnings, without additional visual cues or context. It's also important to consider users with low vision or color blindness, ensuring that information is not solely conveyed through color. Using this color for interactive elements like buttons requires careful consideration of focus states and hover effects to maintain usability for all users. Proper use of ARIA attributes can also improve accessibility.
