Blue Charcoal
General Information about Blue Charcoal
The hex color #010B19, also known as Blue Charcoal, is a very dark, muted shade of blue with almost black appearance. It belongs to the family of blue colors but is characterized by its low saturation and luminance. In the RGB color model, it consists of 0.4% red, 4.3% green, and 9.8% blue. In the CMYK color model, it comprises 96% cyan, 58% magenta, 0% yellow, and 90% black. This composition explains its dark and desaturated appearance. Blue Charcoal is often associated with feelings of calmness, sophistication, and mystery, reflecting its subtle yet impactful presence. Because of its dark nature, the color has limited use cases, because it should be used carefully in designs, especially in combination with text, to ensure readability and accessibility.
The hex color #010B19, also known as Blue Charcoal, presents significant accessibility challenges. Its very low luminance value (close to zero) means that it offers extremely poor contrast against light-colored text or backgrounds. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. Using #010B19 as a foreground or background color requires careful consideration of color contrast ratios. To meet accessibility standards, text or interactive elements displayed with this color necessitate a very light foreground color to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Without such adjustments, content may be illegible for many users, including those with low vision or color blindness. It is important to avoid using #010B19 for critical information or interactive elements without ensuring adequate contrast.
