The hex color #174D81, also known as Chathams Blue, presents specific accessibility considerations for web developers. Its relatively low luminance means that text rendered in this color may not provide sufficient contrast against a white or light-colored background, potentially causing readability issues for users, especially those with visual impairments. 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 ensure they meet these contrast requirements. When using #174D81 for text, consider pairing it with a lighter color for the background, such as white (#FFFFFF) or a very light gray, to enhance readability. Alternatively, if #174D81 is used as a background color, ensure that the text placed on top is a light enough color to meet contrast guidelines. Proper attention to contrast ratios helps ensure that web content is accessible and inclusive for all users.
