The hexadecimal color code #040133, often referred to as Black Rock, is a very dark shade of blue. In the RGB color model, it is composed of 1.57% red, 0.39% green, and 20% blue. This specific combination results in a color that is perceived as deep and somewhat mysterious. Its darkness makes it suitable for applications where a subtle and understated presence is desired. Given its low luminance value, it's crucial to consider accessibility guidelines when using this color, especially in user interfaces or any context where readability is important. The color evokes feelings of night, depth, and quiet sophistication.

The hex color #040133, also known as Black Rock, presents significant accessibility challenges due to its extremely low luminance. Its very dark nature results in poor contrast against lighter backgrounds, potentially making text or graphical elements illegible for users with visual impairments. According to WCAG guidelines, this color fails to meet the minimum contrast ratio requirements for normal text, large text, and user interface components. To ensure accessibility, it is crucial to avoid using #040133 for text or interactive elements on light backgrounds. When using it for decorative purposes, make sure it isn't conveying important information. Consider pairing it with very light hues to enhance readability and overall usability. Furthermore, providing alternative styling options can accommodate individual user preferences and needs.
