When used as a background color, sufficient contrast with text is crucial. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using lighter text colors such as white or light gray can help meet these requirements. Tools like contrast checkers can verify compliance.

Always test your color combinations with accessibility in mind to provide an inclusive user experience. Providing alternative high contrast themes helps all users to properly view the content.
