The hex color #1A4781, also known as Chathams Blue, presents some accessibility challenges, particularly in text-based applications. Its relatively low luminance value of approximately 0.06 makes it difficult to achieve sufficient contrast against lighter backgrounds, such as white (#FFFFFF). According 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 to ensure readability for users with visual impairments. When using #1A4781 for text, it's crucial to pair it with a very light color to meet these contrast requirements. If used as a background color, a lighter text is also needed to achieve the required contrast. Tools like WebAIM's Contrast Checker can be invaluable in assessing and verifying the contrast ratio. Furthermore, avoid using this color as the sole indicator for interactive elements like links or buttons; supplement with additional visual cues such as underlines or borders to ensure usability for all users.
