The hex color #0A4B97, also known as Congress Blue, presents some accessibility challenges, particularly when used as a foreground color against a dark background or as a background color with dark text. Its relatively low luminance value means that the contrast ratio against white may not meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast. This can make it difficult for users with visual impairments to read text or distinguish elements. To improve accessibility, consider using a lighter shade of blue, a brighter complementary color, or pairing it with white to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Adequate color contrast is crucial for ensuring that web content is accessible to all users, including those with low vision or color blindness. Using contrast checking tools during design and development processes is highly recommended to ensure compliance with accessibility standards and best practices.
