The color #0A4A8E, also known as Congress Blue, offers moderate accessibility. Its relatively dark hue provides sufficient contrast against lighter backgrounds, making it suitable for text and interactive elements. However, when paired with darker shades, the contrast ratio may fall below the recommended WCAG (Web Content Accessibility Guidelines) standards, potentially causing readability issues for users with visual impairments. To ensure optimal accessibility, it's essential to test color combinations using contrast checkers. For text, a contrast ratio of at least 4.5:1 against the background is recommended for normal text and 3:1 for large text. Using a lighter color for text on a Congress Blue background, or vice versa, can significantly improve readability and overall user experience. It is also vital to consider that color perception varies, and providing alternative cues like underlines or icons can further enhance accessibility for all users.
