The hex color #0A4680, also known as Congress Blue, presents some accessibility challenges, particularly when used as a background or text color. Due to its relatively low luminance, it needs to be paired with a very light foreground color to ensure sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. It's advisable to use tools that measure color contrast to verify compliance. When used for interactive elements like buttons or links, sufficient contrast is crucial to ensure they are easily identifiable. Using a lighter shade of blue or a completely different, brighter color for hover or focus states can improve usability. Proper semantic HTML and ARIA attributes can further enhance accessibility, especially when used in complex user interfaces. Considering these factors will help create a more inclusive web experience for all users.
