Its relatively low luminance contrast against a white background may not meet WCAG (Web Content Accessibility Guidelines) AA standards for normal text (4.5:1 contrast ratio).

Alternatively, for background usage, consider using darker text.

Furthermore, avoid relying solely on color to convey important information; use text labels or icons in addition to color to cater to users with color blindness.
