With a relatively low luminance, using it as a background color necessitates light-colored text to ensure sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. Tools like contrast checkers can help verify compliance.

For instance, incorporate text labels, icons, or changes in shape or size on hover or focus to ensure usability for all users.
