The hex color #1e4a71, also known as Chathams Blue, presents some accessibility challenges, especially when used for text. Its relatively low lightness value of approximately 0.15 results in a dark appearance. When using this color for text, it is crucial to select a background color that provides sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards. A light background is strongly recommended to ensure readability for users with visual impairments. For instance, pairing it with a background like #FFFFFF (white) yields a contrast ratio of about 11.8:1, which exceeds the WCAG AA and AAA requirements. However, using darker backgrounds can render text illegible and inaccessible. Therefore, always prioritize contrast checks to ensure inclusive design when incorporating #1e4a71 in user interfaces and other visual materials. Tools like WebAIM's contrast checker can be invaluable in making informed decisions.
