General Information About Black Rock

The hex color #0A0B33, often referred to as Black Rock, is a very dark shade of blue tending towards black. In the RGB color model, it is composed of 3.92% red, 4.31% green, and 20% blue. This composition gives it a deep, muted quality. The color is often associated with sophistication, mystery, and depth. It evokes feelings of calmness and introspection. Due to its dark nature, it is often used in designs where a subtle, understated elegance is desired. However, its darkness presents challenges in terms of accessibility, particularly concerning contrast ratios for readability on screens and in print.

The hex color #0A0B33, also known as Black Rock, presents significant accessibility challenges. Its very dark hue results in extremely low contrast against typical light backgrounds used for text or interactive elements. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. Using #0A0B33 for text or important graphical elements requires careful consideration. It is highly recommended to pair it with a very light color, such as white or a very pale yellow, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Furthermore, avoid using this color for interactive elements without clear visual cues beyond color alone, as colorblind users may struggle to identify them. Thoroughly test the color combination with accessibility tools to ensure compliance with accessibility standards and provide an inclusive user experience.
