In the CMYK color model, it consists of 93.86% cyan, 85.71% magenta, 0% yellow, and 80.78% black. This indicates that it is a very deep, saturated color. It is frequently utilized in designs where a subdued and sophisticated visual aesthetic is desired.

Its hexadecimal representation provides a standardized way to represent it across different digital platforms and design tools, making it a versatile choice for designers and developers.

The hex color #030731, often referred to as Black Rock, presents significant accessibility challenges. Its very low luminance value results in extremely poor contrast against standard white backgrounds. This makes it difficult for individuals with visual impairments, including those with low vision or color blindness, to discern text or important visual elements. Web Content Accessibility Guidelines (WCAG) require a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text to ensure readability. Black Rock falls far short of these recommendations. To improve accessibility, consider using lighter text colors such as white or very light grays when using #030731 as a background. Alternatively, use #030731 sparingly, reserving it for purely decorative elements that do not convey critical information. Thorough testing with accessibility evaluation tools is essential to validate sufficient contrast and usability for all users.
