Its low lightness value makes it a very dark color, leading to significant contrast issues if used as a background with similarly dark text. To ensure readability and accessibility, it's crucial to pair this color with very light text, such as white or a light gray. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Using online contrast checkers can help verify compliance.

Providing alternative styling options, such as high-contrast themes, can further enhance accessibility for all users.
