Black Rock

#05052D

General Information about #05052D

The hex color #05052D, often referred to as Black Rock, is an extremely dark shade of blue-black. It resides within the dark end of the color spectrum, possessing minimal luminance and low saturation. Its RGB (Red, Green, Blue) values are R:5, G:5, B:45, indicating a strong blue component compared to red and green. This color is perceived as somber, mysterious, and can even evoke a sense of depth and sophistication when used appropriately. Because of its dark nature, it is commonly used as an alternative to pure black, especially when a slightly softer, less harsh aesthetic is desired. In practical applications, it should be carefully paired with lighter or more vibrant colors to ensure legibility and prevent a visually oppressive atmosphere.

The hex color #05052D, also known as Black Rock, presents significant accessibility challenges, primarily due to its extremely low luminance. This dark hue results in very poor contrast when paired with most other colors, especially lighter shades. Text rendered in #05052D on a white or light-colored background may be illegible or cause eye strain for many users. Individuals with visual impairments, such as low vision or color blindness, will find it particularly difficult to discern content presented in this color. Web developers should avoid using #05052D for essential text or interactive elements unless paired with a very light or saturated color to ensure a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards, ideally a contrast ratio of 4.5:1 for normal text and 3:1 for large text. Careful consideration must be given to the user experience to ensure inclusivity.
