In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, it consists of 96% cyan, 40% magenta, 0% yellow, and 90% black. This indicates that the color is heavily weighted towards blue and black, resulting in its deep and muted appearance.

Blue Charcoal evokes feelings of calmness, sophistication, and stability. Its subtle nature makes it a versatile choice for various design applications where a dark and understated hue is desired.

The color #010F19, also known as Blue Charcoal, presents significant accessibility challenges, primarily due to its very dark nature. When used as a background color, it necessitates extremely light text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Given the darkness of #010F19, designers must meticulously choose text colors, opting for shades close to white or very light pastels to meet these contrast requirements. Failure to do so can render content inaccessible to users with visual impairments, including those with low vision or color blindness. Careful consideration should also be given to interactive elements like buttons and links, ensuring they have clear visual cues and sufficient contrast to be easily identifiable. Adequate testing with accessibility tools is crucial to validate contrast ratios and identify potential usability issues.
