General Information about #0C0B2A

The hexadecimal color code #0C0B2A represents a very dark shade of blue-purple, often referred to as "Black Rock." It's composed of 4.7% red, 4.3% green, and 16.5% blue. In the RGB color model, this translates to 12 red, 11 green, and 42 blue. The color is characterized by its low saturation and luminance, making it appear almost black. Colors like #0C0B2A are often used to evoke feelings of mystery, sophistication, and depth. Due to its low brightness, it's essential to consider contrast ratios when using this color in design to ensure readability and accessibility. It sits within the broader family of dark, cool-toned colors and can be considered a very dark variant of indigo or deep slate.

The hex color #0C0B2A, also known as Black Rock, presents significant accessibility challenges, especially in text-based contexts. Its extremely low luminance results in very poor contrast against common background colors like white. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. #0C0B2A fails to meet these standards against most light backgrounds, making it difficult for users with visual impairments to read. To improve accessibility, it is advisable to pair #0C0B2A with much lighter colors or use it sparingly for decorative elements where readability is not crucial. Using tools to check color contrast ratios during the design process helps ensure compliance with accessibility standards and enhance the user experience for everyone.
