General Information about Blue Charcoal

The hexadecimal color code #010D1A, commonly referred to as Blue Charcoal, is a very dark shade of blue. It belongs to the family of blue colors, but its low saturation and luminance make it appear almost black. In the RGB color model, it consists of 0.4% red, 5.1% green, and 10.2% blue. This color is often used in designs where a subtle, sophisticated, and understated aesthetic is desired. Blue Charcoal can evoke feelings of calmness, depth, and stability. However, due to its darkness, it's essential to use it carefully in designs to ensure sufficient contrast and readability, especially for text and interactive elements. In digital art it is often used in dark scenes to create a somber mood.

The hex color #010D1A, also known as Blue Charcoal, presents significant accessibility challenges due to its very dark nature. Its extremely low luminance results in poor contrast against almost any lighter background, making text or interactive elements nearly impossible to read for users with normal vision. For individuals with low vision or color blindness, the lack of contrast is even more pronounced, rendering content virtually inaccessible. Web developers should avoid using #010D1A for text, icons, or interactive elements unless paired with a very light color that provides a contrast ratio exceeding WCAG (Web Content Accessibility Guidelines) standards (a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text). Careful consideration and testing with accessibility tools are crucial when employing this color to ensure inclusivity and usability for all users. It is best practice to use color contrast analyzers to verify sufficient contrast.
