Blue Charcoal
General Information about Blue Charcoal
Blue Charcoal, represented by the hex code #020819, is a very dark shade of blue. It sits close to black on the color spectrum, possessing minimal luminance. The color's name suggests its resemblance to charcoal with a bluish tint. In the RGB color model, it consists of 0.8% red, 3.14% green, and 9.8% blue. Its primary use is in scenarios where a subtle, dark background is required, often in digital design and sometimes in print. However, its low brightness value necessitates careful consideration of contrast ratios to ensure readability and accessibility, especially when used for text or interactive elements. It is important to remember that color perception can vary across different display devices and individual viewers.
The hex color #020819, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. Its very dark nature results in poor contrast against most background colors, particularly white and lighter shades. This lack of contrast makes it difficult for individuals with visual impairments, including those with low vision or color blindness, to discern text or graphical elements rendered in this color. Web Content Accessibility Guidelines (WCAG) emphasize a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text against its background to ensure readability. Blue Charcoal likely fails to meet these contrast requirements against many backgrounds, necessitating careful consideration and the use of higher luminance foreground colors, such as white or yellow, to provide sufficient contrast and meet accessibility standards. Testing with accessibility evaluation tools is crucial to ensure compliance.

Ensure sufficient contrast with text and interactive elements to adhere to accessibility guidelines and provide a comfortable user experience. Consider using it for sidebars, headers, or footers in a web layout to create visual separation and hierarchy.
