Its relatively low luminance value means that it may not provide sufficient contrast against light backgrounds, potentially making it difficult for users with visual impairments to read. When using this color for text, it's crucial to ensure a high contrast ratio, ideally exceeding 4.5:1 as recommended by WCAG guidelines. This can be achieved by pairing it with very light colors.

Providing alternative cues like borders, underlines, or icons ensures inclusivity and a better user experience.
