The hex color #1A517E, also known as Chathams Blue, presents some accessibility challenges, primarily due to its relatively low contrast against lighter backgrounds. When using this color for text, it's crucial to ensure a sufficient contrast ratio with the background color to meet 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 (14pt bold or 18pt regular). If used with white or very light backgrounds, consider darkening the text color or using a different shade of blue with higher luminance. For interactive elements like buttons or links, providing clear visual cues beyond color, such as underlines or borders, is essential to ensure usability for individuals with color vision deficiencies. Proper testing with accessibility tools is highly recommended to validate compliance.
