The hex color #100B52, also known as Gulf Blue, presents some accessibility challenges, especially when used as a background color for text. Due to its dark nature, it requires very light text (white or near-white) to provide sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using a color contrast checker is crucial to ensure compliance. When using #100B52, avoid pairing it with mid-tone or dark colors for text or interactive elements, as this will likely fail accessibility standards. Consider providing alternative high-contrast themes or using it sparingly for decorative elements rather than functional components.
