The color #040A14, often referred to as Blue Charcoal, is a very dark shade of blue. It resides in the dark end of the color spectrum, imparting qualities of sophistication, depth, and mystery. Its RGB (Red, Green, Blue) values are R:4, G:10, and B:20. In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, it's composed of approximately C:80%, M:50%, Y:0%, and K:92%. This color is mostly used in digital design and print media for backgrounds, text, and other visual elements that require a somber or elegant tone. Blue Charcoal is associated with feelings of calmness, seriousness, and stability, making it a suitable choice for professional and sophisticated designs.

The hex color #040A14, also known as Blue Charcoal, presents significant accessibility challenges due to its very low luminance. Its contrast ratio against white (#FFFFFF) is extremely poor, failing to meet WCAG (Web Content Accessibility Guidelines) AAA standards for normal text. This means that text displayed in #040A14 on a white background will be difficult, if not impossible, for many users to read, especially those with visual impairments. Similarly, using white text on a #040A14 background would be problematic. To improve accessibility, consider using lighter shades of gray or other colors with significantly higher luminance. Tools like contrast checkers can help to evaluate color combinations and identify accessible alternatives. When designing with #040A14, it's vital to prioritize readability and inclusivity by ensuring sufficient contrast.
