The hex color #0A0034, also known as Black Rock, is a very dark shade of blue-black. In the RGB color model, it is composed of 3.92% red, 0% green, and 20.39% blue. This results in a predominantly blue hue with a significant reduction in brightness, leading to its dark appearance. In the CMYK color model, it is composed of 81% cyan, 100% magenta, 0% yellow, and 80% black. This color is often associated with feelings of mystery, depth, and sophistication. Its use in design can create a sense of elegance and formality. It's most suitable for applications where a subtle and understated color is desired, and should be paired carefully with lighter colors to ensure readability and visual balance.

The hex color #0A0034, also known as Black Rock, presents significant accessibility challenges, especially for users with visual impairments. Its very low luminance value results in extremely poor contrast against both white and light-colored backgrounds. This makes text and other important visual elements difficult to discern. Using #0A0034 for text or interactive elements is strongly discouraged unless paired with a very light or white color to achieve a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards of at least 4.5:1 for normal text and 3:1 for large text. Providing alternative high-contrast themes or controls for users to adjust the color scheme is highly recommended to ensure inclusive and accessible design.
