Its relatively low luminance can make it difficult for users with visual impairments to discern text or interactive elements. To ensure accessibility, it's crucial to maintain a sufficient contrast ratio, ideally meeting or exceeding the WCAG (Web Content Accessibility Guidelines) AA standard of 4.5:1 for normal text and 3:1 for large text.

Providing sufficient spacing around elements with this color will also improve legibility. Testing with accessibility tools and getting feedback from users with disabilities is highly recommended.
