The low red and green values, combined with the dominant blue, give it its unique character and visual impact.

The hex color #0A0A36, also known as Black Rock, presents significant accessibility challenges, particularly in web design. Its extremely low luminance results in very poor contrast against typical light-colored backgrounds, such as white or light gray. This lack of contrast makes text and other visual elements difficult for users with visual impairments to perceive, including those with low vision or color blindness. To ensure accessibility, it is crucial to avoid using #0A0A36 for text or important interface elements unless paired with a very light or even white foreground color. 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. Using tools to evaluate contrast ratios is essential when incorporating this color into designs. Failure to meet these guidelines can lead to an inaccessible and frustrating user experience.
