When used as a background color, it requires careful consideration of the foreground text or elements. Due to its dark nature, light-colored text (e.g., white or very light shades of yellow or green) is necessary to ensure sufficient contrast for readability, ideally meeting WCAG (Web Content Accessibility Guidelines) AA or AAA standards. Using a color contrast checker is highly recommended to verify compliance. Furthermore, avoid using this color for essential visual cues without providing alternative indicators, such as text labels or icons, especially for users with low vision or color blindness. When designing user interfaces, test the color combination with different user groups and accessibility testing tools to ensure usability for everyone.
