When used as a background color, it requires very light text to ensure readability for individuals with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Using online contrast checkers can help determine suitable foreground colors. Avoid pairing this color with other dark shades, as this will significantly reduce readability.

Consider adding a subtle text shadow or outline to improve legibility.
