Black Rock
General Information
The hex color code #0A013B, often referred to as 'Black Rock', is a very dark shade of blue-purple. It resides in the lower range of the color spectrum due to its low hexadecimal values. In the RGB (Red, Green, Blue) color model, it is composed of 3.92% red, 0.39% green, and 23.14% blue. This composition explains its deep, muted tone. In the CMYK (Cyan, Magenta, Yellow, Black) color model, it consists of 83% cyan, 98% magenta, 0% yellow, and 77% black. Colors similar to #0A013B are often associated with sophistication, mystery, and depth. Due to its darkness, it is typically used as an accent or background color, rather than a primary color, to avoid overwhelming the senses.
The hex color #0A013B, also known as Black Rock, presents significant accessibility challenges, especially in text-based applications. Its extremely low lightness value (very close to black) results in poor contrast against most backgrounds. Using this color for text or interactive elements requires careful consideration. To ensure readability and usability, it's crucial to pair it with a very light color, such as white or a pale yellow, to achieve a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Failure to meet these contrast requirements can exclude users with visual impairments, making content difficult or impossible to perceive. Careful testing with accessibility tools is essential to validate the color combination. Beyond text, its use in graphical elements should be similarly scrutinized for sufficient discernibility.

Applications
Website Background
In web design, #0A013B can be used as a background color for sections where a sense of sophistication and mystery is desired. When applying this color, ensure that the foreground text is of a contrasting color such as white or yellow to maintain readability. It can be combined with lighter shades of purple or blue to create a visually appealing and balanced color scheme. This color works best when implemented strategically, to highlight content or create a dramatic aesthetic effect, rather than being applied across entire web pages. Its use can add depth and intrigue to a design when balanced with lighter elements.
Formal Wear
In fashion design, #0A013B can be used for formal wear, creating a sophisticated and elegant look. When using this color in garment design, consider pairing it with silver or gold accessories for contrast. The deep color allows it to serve as a neutral canvas to allow brighter colors or intricate designs to stand out. The shade is especially well-suited for evening wear, adding a touch of mystery and refinement. Consider using different textures within the design to add visual interest since the color itself is very dark and monochromatic.
Graphic Design
In graphic design, #0A013B can be used to create a dark and moody atmosphere, perfect for posters or album covers. The deep hue evokes a sense of depth and can be used to add intrigue. When combining it with brighter colors like neon blues or purples, it amplifies the contrast, making designs pop. The color can be further enhanced with subtle gradients or textures to add more complexity and prevent it from looking flat. This is very useful for designs that need to have a futuristic theme.
