The hex color #01041A, also known as Blue Charcoal, is a very dark shade of blue with minimal presence of red and green. It's composed of 0.4% red, 1.6% green, and 10.2% blue, making it lean heavily towards the blue end of the color spectrum. This color is often associated with sophistication, mystery, and depth. Due to its dark nature, it has a low luminance value, which means it reflects very little light. In the RGB color model, it's represented as R:1, G:4, B:26. In the CMYK color model, it consists of 96% cyan, 85% magenta, 0% yellow, and 90% black. Its hexadecimal representation is commonly used in web design and digital graphics to define color values.

The hex color #01041A, also known as Blue Charcoal, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value (very dark) results in poor contrast against most background colors, especially white (#FFFFFF). This can make text and other visual elements difficult or impossible to read. To ensure accessibility, it is crucial to use a very light color for text and interactive elements when using #01041A as a background. Following WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Thoroughly test the color combination with accessibility tools and consider user feedback to avoid usability issues. Providing alternative high-contrast themes is also beneficial.
