Its relatively low luminance can pose challenges in ensuring sufficient contrast with both light and dark foreground text. When using this color for backgrounds, it is imperative to verify that the text placed on top meets the WCAG (Web Content Accessibility Guidelines) AA or AAA standards for contrast ratio. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Tools are available to check contrast ratios and adjust colors as needed.

Thorough testing with accessibility evaluation tools and user feedback will ensure an inclusive experience.
