The hexadecimal color code #0A0B2A, commonly referred to as Black Rock, is a dark shade of blue-purple. In the RGB color model, it is composed of 3.92% red, 4.31% green, and 16.47% blue. When represented in the CMYK color model, it consists of 76.13% cyan, 73.87% magenta, 0% yellow, and 83.53% black. This color is often associated with depth, mystery, and sophistication. Its low luminance makes it unsuitable for use as a primary background color in user interfaces, but it can be effectively used as an accent color when paired with lighter hues to provide sufficient contrast. Black Rock can evoke feelings of calmness and introspection, making it a popular choice for designs aiming for a serene or contemplative mood.

The hex color #0A0B2A, also known as Black Rock, presents significant accessibility challenges due to its very low luminance. With such a dark shade, ensuring sufficient contrast is paramount. For text, a very light color such as white (#FFFFFF) or a bright yellow (#FFFF00) would be necessary to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. It's crucial to use contrast checking tools to verify compliance. In user interface design, consider using this color sparingly for backgrounds or accents and avoid using it for interactive elements without careful consideration of contrast. Providing alternative high-contrast themes is also advisable to accommodate users with visual impairments or those browsing in bright environments.
