General Information about Blue Charcoal

The hexadecimal color code #000820, also known as Blue Charcoal, represents a very dark shade of blue. In the RGB color model, it is composed of 0% red, 3.14% green, and 12.55% blue. This color is often associated with sophistication, depth, and a sense of mystery. In color theory, Blue Charcoal is a tertiary color, resulting from the mixture of a primary color (blue) with black. Its muted tone makes it versatile for various applications, particularly in designs where a subtle, calming effect is desired. Due to its low luminance, it's essential to pair Blue Charcoal with lighter colors to ensure adequate contrast and readability, especially in text and user interface elements. The color evokes feelings of tranquility and can be used to represent both natural themes (like a night sky) or modern concepts (like technology and futurism).

The hex color #000820, also known as Blue Charcoal, presents significant accessibility challenges, especially in web design. Due to its very dark nature, it provides extremely low contrast against lighter text or backgrounds, potentially violating WCAG (Web Content Accessibility Guidelines) standards. To ensure readability and usability for all users, including those with visual impairments, it is crucial to pair this color with very light shades. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Using color contrast analyzers is essential to verify compliance. Avoid using #000820 for primary text or interactive elements without careful consideration of contrast. Instead, it can be used sparingly for decorative elements or as a background for very light text to create a specific mood or aesthetic, while always prioritizing accessibility.
