Its relatively dark hue means that careful attention must be paid to color contrast, especially concerning text. To ensure readability and comply with WCAG guidelines, it's crucial to use this color with lighter background colors for text elements, or conversely, use it as a background with light-colored text. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet accessibility standards.
