#000B1C

General Information

Blue Charcoal, represented by the hexadecimal color code #000B1C, is a very dark shade of blue. In the RGB color model, it consists of 0% red, 4.3% green, and 11% blue. This composition results in a color that is perceived as deep, muted, and almost black. The name 'Blue Charcoal' aptly describes its appearance, reminiscent of charcoal with a subtle hint of blue. Due to its darkness, it is often used to create a sense of depth, mystery, or sophistication in designs. However, its low luminosity also means it requires careful consideration regarding contrast and readability, particularly when used in text or user interface elements. It belongs to the family of cool colors and can evoke feelings of calmness or seriousness, depending on its context.

The color #000B1C, also known as Blue Charcoal, presents significant accessibility challenges, particularly in web design. Its extremely dark hue results in very low contrast against standard white backgrounds, making text and other elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast ratios are crucial for ensuring readability and usability. To meet these guidelines, when using #000B1C for backgrounds, it is imperative to pair it with very light text colors, such as white or shades of yellow. Conversely, if using it for text, a very light background is necessary. Developers must use contrast checking tools to verify compliance with accessibility standards to ensure content is accessible to all users, including those with low vision or color blindness. Failure to address contrast issues can exclude a significant portion of the user base and diminish the overall user experience.
