The hex color #0A4563, also known as Astronaut Blue, presents some accessibility challenges, particularly in text-based applications. Its low luminance value necessitates careful consideration of contrast ratios against background colors. To ensure readability, it's crucial to pair it with lighter shades, ideally whites or very pale yellows, to achieve a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When used for interactive elements like buttons or links, sufficient contrast is vital to help users with visual impairments distinguish these elements.

Testing with accessibility tools and user feedback are essential steps to validate the accessibility of designs incorporating #0A4563.
