General Information about #0A052F

The hexadecimal color code #0A052F, often referred to as Black Rock, signifies a very dark shade of blue-leaning purple. It is composed of 3.92% red, 1.96% green, and 18.43% blue. In the RGB color space, it translates to R:10, G:5, B:47. The CMYK representation is C:79, M:89, Y:0, K:82, indicating a high proportion of cyan and magenta to achieve its deep, muted tone. This color is more commonly found in digital designs and artistic renderings than in everyday objects due to its low luminance. Its shadowy nature makes it suitable for creating a sense of depth, mystery, or sophistication. Its dark nature does make it difficult to work with for text elements or other elements requiring high visibility.

The color #0A052F, a deep, dark hue, presents significant accessibility challenges, particularly in web design. Due to its extremely low luminance, text rendered in this color against a white or light background would likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. To ensure readability and usability for all users, including those with visual impairments, it is crucial to avoid using #0A052F for text or interactive elements without careful consideration. If this color is essential to the design, it must be paired with a very light or white foreground color to achieve sufficient contrast. Tools like contrast checkers can help verify compliance. Furthermore, avoid using this color alone to convey important information, such as error states, as users with color blindness may not be able to distinguish it effectively. Providing supplementary cues, like text labels or icons, is recommended to enhance accessibility.
