When used as a background, it necessitates light-colored text to ensure readability for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, according to WCAG guidelines. Using tools to check color contrast is essential.

For users with color vision deficiencies, ensure that the information is still understandable when color is not distinguishable. Thoughtful application of this color can enhance the aesthetic appeal while maintaining accessibility standards.
