General Information about Blue Charcoal

The hexadecimal color code #000D1B, also known as Blue Charcoal, is a very dark shade of blue. It is composed of 0% red, 5.1% green, and 10.6% blue. In the RGB color model, this translates to (0, 13, 27). The color has very low saturation and luminance, making it appear almost black. Blue Charcoal is often associated with feelings of calmness, sophistication, and stability. It is frequently used in designs where a subtle, understated appearance is desired. Due to its low luminance, it's essential to carefully consider contrast when using this color, particularly for text and interactive elements. It can be used for backgrounds as well, providing other elements are light enough to create sufficient contrast.

The color #000D1B, also known as Blue Charcoal, presents significant accessibility challenges, especially in text-based contexts. Its extremely low luminance value makes it difficult to achieve sufficient contrast against lighter backgrounds, potentially violating WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. This can lead to readability issues for users with visual impairments. To ensure accessibility, it's crucial to pair this color with very light shades, and even then, careful testing with accessibility evaluation tools is highly recommended. Avoid using this color for important information, links, or interactive elements unless a sufficient contrast ratio of at least 4.5:1 for normal text and 3:1 for large text can be guaranteed. When using this color for decorative purposes, such as backgrounds or accents, ensure that it does not interfere with the readability of any content placed on top of it.
