Due to its extremely low luminance, it approaches black, making it suitable for creating a sense of mystery, sophistication, or depth in various applications.

The hex color #0D0034, also known as Black Rock, presents significant accessibility challenges, particularly in web design. Its extremely low luminance value of approximately 0.003 makes it difficult to achieve sufficient contrast against lighter backgrounds, thus failing WCAG (Web Content Accessibility Guidelines) standards for text and non-text contrast. To ensure accessibility, it is crucial to avoid using #0D0034 for text or interactive elements unless paired with an exceptionally light color. A contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text to meet WCAG AA standards. Thoroughly testing color combinations with accessibility tools is essential to guarantee usability for individuals with visual impairments. Alternatives include using lighter shades or complementary colors to create accessible designs.
