General Information about Black Rock

The hexadecimal color #100C34, commonly referred to as Black Rock, is a very dark, muted color. It resides within the blue-violet hue family, but its low saturation gives it a near-neutral appearance. In the RGB color model, it is composed of 6.27% red, 4.71% green, and 20.39% blue. This composition explains its dark, slightly blueish tint. In the CMYK color model, which is used for printing, #100C34 consists of 69% cyan, 77% magenta, 0% yellow, and 80% black. This indicates that it requires a significant amount of cyan and magenta to achieve its particular shade. Its primary use in digital design is often limited due to accessibility concerns related to low contrast, but it can find niche applications in areas where a dark, subtle tone is desired.

The hex color #100C34, also known as Black Rock, presents distinct accessibility challenges. Its extremely low luminance contrast against white text makes it nearly unreadable for individuals with normal vision. It utterly fails WCAG's AAA standards for contrast ratio, necessitating careful consideration of text and background color pairings. Using #100C34 for primary text or interactive elements is strongly discouraged due to its severe impact on readability, especially for users with visual impairments or color vision deficiencies. When using this color, ensure that all text has sufficient contrast. A minimum contrast ratio of 4.5:1 is recommended for normal text and 3:1 for large text. Consider pairing it with significantly lighter shades or using it sparingly for decorative purposes where readability is not critical. Tools like contrast checkers can help determine appropriate color combinations. Using a very bright color in front of the color #100C34 should solve contrast issues. Always test your color choices with users, especially those with disabilities, to ensure accessibility.
