The hex color #0A3C63, also known as Astronaut Blue, presents specific accessibility considerations for web development. Its dark nature means that it requires light-colored text for sufficient contrast. Using a color contrast checker is crucial to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text, as recommended by WCAG guidelines. Without adequate contrast, users with visual impairments may struggle to read content.

Consider providing alternative high-contrast themes to enhance usability for all users. This attention to detail can significantly improve the inclusivity of your design.
