The hex color #0A0A5A, also known as Gulf Blue, presents some accessibility challenges, especially when used for text. Its low lightness value means that it requires a very light text color to achieve sufficient contrast for readability, adhering to 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 pairing #0A0A5A with white (#FFFFFF), the contrast ratio is adequate. However, using it with darker shades may render the text illegible for users, particularly those with visual impairments. In design, consider using #0A0A5A sparingly for large elements or backgrounds where text is minimal or absent, or ensure it's paired with a sufficiently light color to meet accessibility standards, enhancing usability for all users.
