General Information about #050730

The hex color #050730, often referred to as 'Black Rock,' is a very dark shade of blue-leaning black. In the RGB color model, it is composed of 2.0% red, 2.7% green, and 18.8% blue. This means that blue light is significantly dominant in its composition, leading to its dark, subtly bluish hue. In the CMYK color model, which is often used for printing, it consists of 89% cyan, 86% magenta, 0% yellow, and 81% black. This indicates a high level of color saturation with a strong black undertone. Due to its extreme darkness, #050730 is primarily used for creating depth, contrast, or a sophisticated, subdued atmosphere in design applications. Its hexadecimal code makes it easy to specify precisely in digital design and web development contexts.

The hex color #050730, also known as Black Rock, presents significant accessibility challenges, particularly in web design. Its extremely dark nature results in very low contrast when paired with most text colors, potentially violating WCAG (Web Content Accessibility Guidelines) standards. To ensure readability and usability, especially for users with visual impairments, it is crucial to use #050730 with very light text colors, such as white (#FFFFFF) or very light grays. Even then, careful evaluation is necessary to meet contrast ratio requirements. Using tools that measure contrast ratios is highly recommended before implementing this color in a user interface. Furthermore, consider providing alternative color schemes that offer better contrast for users who may need them. Avoid using this color for essential interactive elements without proper contrast considerations, as it can render those elements inaccessible.
