The color #1A4772, a deep, muted blue, presents some accessibility challenges, particularly when used as text against a white background. Its relatively low luminance (brightness) results in a low contrast ratio, potentially making it difficult for users with visual impairments to read. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) AA standards. When using #1A4772, careful consideration should be given to its pairing with other colors. A lighter background or using it for larger graphical elements can help improve readability. Always test color combinations using accessibility tools to ensure sufficient contrast for all users, including those with low vision or color blindness. Also, consider providing alternative ways to convey information, like icons or labels, in addition to color.
