Its low luminance results in poor contrast against lighter backgrounds, making it difficult for users with visual impairments to perceive text or graphical elements. According to WCAG guidelines, this color fails to meet the minimum contrast ratios for both normal and large text sizes.

When using this color, consider its impact on users with low vision or color blindness and provide alternative styling options for those who need them.
