General Information about Black Rock

The hexadecimal color #0A0A2E, also known as Black Rock, is a dark shade of blue-violet. It is composed of 3.92% red, 3.92% green, and 18.04% blue. In the RGB color space, it has the numerical values (10, 10, 46). Its CMYK representation is (0.78, 0.78, 0.00, 0.82). This color is often associated with depth, mystery, and sophistication. Due to its high blue content, it can evoke feelings of calmness and tranquility, while its darkness lends a sense of formality and elegance. Black Rock is not a commonly used color in mainstream designs because of its darkness, but it can be effective in niche applications where a specific mood or aesthetic is desired. It should be carefully used in combination with lighter colours to create visual balance.

The hex color #0A0A2E, also known as Black Rock, presents significant accessibility challenges, particularly in text-based contexts. Its extremely low luminance value results in very poor contrast against almost all background colors, especially white. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Black Rock fails to meet these criteria when paired with light backgrounds. Therefore, it is strongly advised to avoid using this color for text or interactive elements without careful consideration. Designers should either use a much lighter color or substantially increase the text size and weight to improve readability. Additionally, consider providing alternative color schemes for users with visual impairments or color blindness to ensure inclusivity and a positive user experience. Thorough testing with accessibility tools is crucial to validate that sufficient contrast is achieved before deployment.
