#000B1A

General Information

The hex color #000B1A, also recognized as Blue Charcoal, is a very dark shade of blue, almost approaching black. Its RGB values are R:0, G:11, B:26, representing a minimal presence of red and green, with a slightly more pronounced blue component. In the CMYK color model, it comprises 100% cyan, 58% magenta, 0% yellow, and 90% black. This indicates that it's primarily composed of cyan and black inks, resulting in its deep, muted appearance. Blue Charcoal evokes feelings of sophistication, depth, and tranquility. It's often associated with elegance, mystery, and the night sky. Due to its low luminance, it requires careful consideration in design to ensure sufficient contrast with other elements.

The hex color #000b1a, also known as Blue Charcoal, presents several accessibility considerations for web developers. Its extremely low luminance value results in very poor contrast against standard white backgrounds, failing WCAG's AA and AAA contrast ratio requirements. This can make text or interactive elements using this color unreadable for users with visual impairments, including those with low vision or color blindness. To ensure accessibility, it's crucial to pair #000b1a with significantly lighter colors for text and interface elements. Alternative approaches include using a color contrast analyzer to verify sufficient contrast ratios or exploring lighter shades within the blue-charcoal family that offer improved readability while maintaining the desired aesthetic. Developers should also consider providing alternative color themes or user controls that allow individuals to customize the color scheme according to their preferences and needs, enhancing overall usability and inclusivity.
