Its low luminance can cause issues with text legibility if used as a text color on a white or light background. Sufficient contrast is crucial to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text.
