Due to its dark nature, it has low contrast against similarly dark backgrounds, making it difficult for users with visual impairments to read text or distinguish elements. Web developers should ensure sufficient contrast by pairing it with lighter colors for text, icons, and interactive components. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as specified by WCAG guidelines.

Additionally, avoid using this color as the sole indicator of interactive elements, as colorblind users may not be able to perceive the difference.
