In the CMYK color model, it consists of 77% cyan, 100% magenta, 0% yellow, and 80% black. This dark hue conveys a sense of mystery, depth, and sophistication. Due to its low luminance value, it is generally used as an accent color, or when a dark background is desired. When utilizing this color, it is important to consider contrast ratios to ensure readability, especially when used for text or interactive elements. In design, Black Rock can bring a sense of understated elegance.

The hex color #0C0034, also known as Black Rock, presents significant accessibility challenges due to its very low luminance. Its dark nature results in extremely poor contrast against typical light backgrounds like white or light gray. This poses readability issues for users with visual impairments, including those with low vision, color blindness, or cataracts. Ensuring sufficient contrast is crucial for web accessibility, as mandated by WCAG (Web Content Accessibility Guidelines). A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Black Rock falls far short of these recommendations when paired with most light backgrounds. To improve accessibility, it's essential to use Black Rock sparingly and always pair it with a very light color for text or interactive elements, carefully verifying that the contrast ratio meets accessibility standards. Providing alternative high-contrast themes is also a beneficial approach.
