The color is used infrequently in marketing materials but has found its place in websites related to finance and government.

The hex color #110a2b, also known as Black Rock, presents significant accessibility challenges, especially for users with visual impairments. Its extremely low luminance value (very dark) results in very poor contrast against most background colors, particularly white. This lack of contrast makes text and graphical elements rendered in this color difficult to read or discern. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background. #110a2b falls far short of these requirements when paired with lighter colors, potentially excluding users with low vision. To ensure accessibility, it's crucial to use this color sparingly and always pair it with extremely light hues such as white or light yellow to achieve sufficient contrast. Avoid using #110a2b for critical information or interactive elements without proper contrast considerations. Implementing contrast checking tools during the design process is highly recommended.
