Its relatively moderate luminance necessitates careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against the background color. Using white or very light shades of yellow or green as text colors could potentially meet these requirements. Tools such as contrast checkers can be used to verify compliance.
