General Information about Blue Charcoal

The color #000D13, also known as Blue Charcoal, is a very dark shade of blue with a hint of black. In the RGB color model, it consists of 0% red, 5.5% green, and 7.5% blue. This composition results in a deep, muted tone that evokes feelings of sophistication, mystery, and depth. Due to its high black component and low brightness, it is generally used as a background color or an accent color in design. In hexadecimal notation, it is represented as #000D13, which is often used in web design and graphic design to specify colors precisely.

The hex color #000D13, also known as Blue Charcoal, presents significant accessibility challenges due to its very low luminance. With such a dark shade, it's crucial to use contrasting text colors like white or very light shades of yellow or green to ensure readability. The contrast ratio should ideally meet WCAG (Web Content Accessibility Guidelines) standards of at least 4.5:1 for normal text and 3:1 for large text. Without sufficient contrast, users with visual impairments, including those with low vision or color blindness, may struggle to perceive the content. Careful consideration should be given to the background and foreground color combinations to avoid creating a barrier to access.
