Its relatively dark hue means it generally provides sufficient contrast when used with lighter text or background colors. However, it's crucial to verify contrast ratios, especially when pairing it with mid-tone shades, to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using tools like contrast checkers is highly advisable during the design process.

Careful selection of foreground and background pairings is key to making content accessible and user-friendly.
