General Information about Blue Charcoal

The hex color #060915, often referred to as Blue Charcoal, is a very dark shade of blue leaning towards black. It is composed of 2.4% red, 3.53% green, and 8.24% blue. In the RGB color space, this equates to R:6, G:9, B:15. The CMYK representation is C:60, M:40, Y:0, K:92, meaning it's primarily composed of cyan and magenta with a heavy dose of black. This color evokes feelings of sophistication, mystery, and depth. Due to its low lightness value, it should be used carefully in designs to ensure sufficient contrast and readability against lighter elements. Its subtle blue undertone distinguishes it from pure black, adding a touch of uniqueness and elegance. It's often favored in minimalist designs and applications requiring a subtle, understated aesthetic.

The hex color #060915, also known as Blue Charcoal, presents significant accessibility challenges. Its extremely low luminance value of 0.005 makes it difficult to perceive against most backgrounds, especially for users with visual impairments. The contrast ratio against a white background (e.g., #FFFFFF) is approximately 41.67:1, exceeding the WCAG's AAA requirement of 7:1 for text and 4.5:1 for user interface components. However, achieving sufficient contrast with lighter colors is crucial. Ensure foreground elements are significantly brighter (higher luminance) to meet accessibility standards. Avoid using this color for essential textual information or interactive elements without careful consideration of contrast ratios and alternative color schemes. Testing with accessibility tools and real users is highly recommended to validate the design's usability for all users, especially those with low vision or color blindness.
