General Information about Black Rock

#100B29, also known as Black Rock, is a deep, dark shade of purple-blue leaning towards black. It evokes feelings of mystery, sophistication, and introspection. In color psychology, dark colors like Black Rock are often associated with power, elegance, and formality. Due to its low lightness value, it is primarily used as an accent color or in backgrounds where high contrast is desired. In web design, Black Rock can create a sense of depth and sophistication. However, it's essential to use it sparingly and pair it with lighter colors to maintain readability and accessibility. The RGB values are R:16, G:11, B:41, and the CMYK values are C:61, M:73, Y:0, K:84.

The hex color #100B29, also known as Black Rock, presents a significant challenge for accessibility, especially in text-based applications. Its extremely low lightness value results in very poor contrast against white backgrounds, making it difficult for users with visual impairments to read text displayed in this color. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Black Rock falls far short of these recommendations. To improve accessibility, consider using lighter colors for text or a lighter shade as the background when using Black Rock as an accent color. Also, avoid using this color for critical interface elements or important information, as it may be missed by many users. Providing alternative color schemes can also significantly enhance usability for users with different visual needs.
