Its relatively low luminance value means it may not provide sufficient contrast against lighter backgrounds, potentially making text or other visual elements difficult to discern. When using this color for text, it's crucial to ensure a high contrast ratio with the background color, ideally meeting WCAG (Web Content Accessibility Guidelines) AA or AAA standards. Tools like contrast checkers can help determine if the contrast ratio is sufficient. Avoid pairing it with similar dark hues, which can further reduce readability. Consider using a lighter shade of gray, white, or a complementary color as a background to improve accessibility. For interactive elements, ensure there are additional visual cues besides color to indicate state changes, such as focus or hover states.
