General Information about Blue Charcoal

Blue Charcoal, represented by the hex code #001112, is a very dark shade of cyan-blue. It is composed of 0% red, 6.7% green, and 7.1% blue. In the RGB color space, it essentially has minimal light intensity, making it a very subdued color. The color is often associated with feelings of depth, sophistication, and tranquility. It's often used to evoke a sense of calm and can provide a grounding effect in designs. This color is more commonly used for backgrounds or accents due to its dark nature. When used effectively, it can add a touch of elegance, but one must be cautious to maintain suitable contrast with other elements in order to ensure readability and accessibility, especially for text.

The hex color #001112, also known as Blue Charcoal, presents significant accessibility challenges. Its extremely low luminance value results in very poor contrast against white text, making it difficult for users to read. According to WCAG guidelines, sufficient contrast is essential for readability, especially for users with visual impairments. To improve accessibility, it is crucial to use a light text color, such as white (#FFFFFF) or a very light gray, against this dark background. However, even with white text, the contrast ratio may still fall below the recommended levels for optimal accessibility. Therefore, consider lightening the base color or choosing an entirely different color palette to ensure your content is accessible to all users, especially those with low vision or color blindness. Proper contrast ensures readability and a better user experience. Testing with accessibility tools is highly recommended.
