Black Rock

#0A0B2B

General Information about #0A0B2B

The hex color #0A0B2B, often referred to as Black Rock, is a very dark shade of blue-black. It's composed of 3.92% red, 4.31% green, and 16.86% blue. In the RGB color model, this translates to R:10, G:11, B:43. Its low values across the RGB spectrum contribute to its dark, almost black appearance. This color is more frequently utilized in digital design where subtle shades and hues can be accurately represented. Its darkness lends itself well to creating a sense of depth, mystery, or sophistication in designs. While not a 'true' black, it offers a slightly more nuanced alternative, potentially adding visual interest without the starkness of pure black (#000000).

The hex color #0A0B2B, also known as Black Rock, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low lightness value of approximately 3% means that any text or interactive elements using this color as a background would require very light foreground colors to meet WCAG (Web Content Accessibility Guidelines) contrast requirements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #0A0B2B, achieving these ratios often necessitates using nearly white text, which might not always be aesthetically desirable or align with the overall design. It's crucial to test color combinations with accessibility tools to ensure readability and usability for all users, including those with color blindness or low vision. When using this color, provide alternative styling or options for users to customize the color scheme to improve accessibility.
