General Information about #09072D

The hex color code #09072D, often referred to as 'Black Rock', is a deep, dark shade of blue-leaning black. In the RGB color model, it is composed of 9 red, 7 green, and 45 blue components. This translates to approximately 3.5% red, 2.7% green, and 17.6% blue. Given its high blue component and low red and green, the color leans strongly towards the blue end of the spectrum, though its darkness largely mutes the vibrancy typically associated with blue. The color is typically perceived as a dark, muted, and somewhat mysterious hue. Due to its low brightness value, it is often associated with feelings of depth, sophistication, and even melancholy. In various applications, it can create a sense of elegance or solemnity.

The hex color #09072D, also known as Black Rock, presents significant accessibility challenges, primarily due to its very dark nature. When used as a background color, it requires extremely light text to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This dark hue will likely fail to meet these standards with many common text colors. Therefore, it is crucial to carefully select contrasting colors and to test the color combination with accessibility evaluation tools. Using this color for interactive elements like buttons or links requires extra caution. Visual cues, beyond just color, should be implemented to ensure usability for users with visual impairments. Consider adding borders, underlines, or icons to enhance recognition and interaction. Always prioritize providing a positive user experience by carefully considering accessibility when using such a dark color.
