When used as a background color, it's essential to ensure sufficient contrast with the foreground text color. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG AA standards.

Consider providing alternative color schemes to enhance user experience for individuals with visual impairments.
