General Information about #11092C

The hex color code #11092C, often referred to as "Black Rock," is a dark, muted shade of purple with slight undertones of blue. In the RGB color model, it consists of 6.67% red, 3.53% green, and 17.25% blue. This combination creates a color that is perceived as mysterious, deep, and somewhat somber. In the HSV (hue, saturation, value) system, its hue is around 255 degrees, saturation is at 79.5%, and its value is at 17.3%. This indicates a color that leans heavily towards the purple spectrum, is highly saturated, and relatively dark. The color's darkness is due to the low value component, making it suitable for use as a background color or in situations where a sense of depth is desired.

The hex color #11092C, also known as Black Rock, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance value results in very poor contrast against standard white backgrounds. According to WCAG guidelines, this color combination would fail even the strictest AAA compliance level. To ensure readability and inclusivity, it is crucial to pair this dark hue with substantially lighter colors. When used as a background, opt for text colors like white, light gray, or vibrant pastels. Avoid using it for essential interface elements like buttons or links without careful consideration of contrast ratios. For graphical elements, consider using it sparingly as an accent color rather than a primary fill, especially where visual clarity is paramount. Proper use of ARIA attributes can also enhance accessibility for screen reader users.
