Its relatively low lightness value means it necessitates careful pairing with text and background colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using this color as a background requires light-colored text to meet these standards, while using it for text demands a light background.
