The hex color #1F517C, also known as Chathams Blue, presents some accessibility considerations for web developers. Its relatively dark hue means it requires careful pairing with text and other elements to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text.

It's crucial to test color combinations using accessibility tools to verify compliance. Furthermore, avoid relying solely on color to convey information, as users with color vision deficiencies may struggle to differentiate between elements. Provide alternative cues like text labels or icons to ensure inclusivity. Remember that accessible design benefits all users, creating a more user-friendly and understandable experience.
