General Information about Black Rock (#0B0729)

#0B0729, known as Black Rock, is a very dark, muted shade of blue-black. It sits deep within the color spectrum, characterized by extremely low saturation and brightness values. This hex code translates to RGB values of R:11, G:7, and B:41. In the CMYK color model, it's approximately C:73, M:83, Y:0, K:84. The color is often associated with feelings of sophistication, mystery, and depth. Due to its darkness, it is rarely used as a primary color but more often as an accent or background element to add contrast or create a subtle, moody atmosphere. Black Rock leans towards the cooler side of the color wheel, making it a good choice for designs that require a sense of calm or understated elegance.

The hex color #0B0729, also known as Black Rock, presents significant accessibility challenges, particularly in text-based applications. Its extremely low lightness value results in very poor contrast against almost any background color. According to WCAG guidelines, sufficient contrast is crucial for readability and usability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Black Rock falls far short of these recommendations when paired with typical light backgrounds like white or light gray. To improve accessibility, it's strongly advised to use Black Rock sparingly, if at all, for text. When it's unavoidable, ensure a high-contrast background is used, and preferably test the color combination with accessibility tools to confirm compliance with WCAG standards. Alternatives with higher lightness values should also be considered to enhance overall accessibility.
