General Information about Blue Charcoal

The hexadecimal color code #040816, also known as Blue Charcoal, is a very dark shade of blue, almost appearing black. It is composed of 1.57% red, 3.14% green, and 8.63% blue. In the RGB color model, it is represented as RGB(4, 8, 22). This color is frequently used to evoke feelings of sophistication, elegance, and mystery due to its deep and subdued nature. In the context of additive color mixing, this color is formed by a minimal contribution of each of the primary colors. Blue Charcoal is often found in design palettes aiming for a dark, rich aesthetic, though care must be taken to ensure sufficient contrast when used with text or other design elements.

The color #040816, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely dark nature. With very low contrast against white text, it fails to meet WCAG (Web Content Accessibility Guidelines) standards for readability. Specifically, the contrast ratio is far below the recommended 4.5:1 for normal text and 3:1 for large text. Therefore, using #040816 as a background color with light text or as a text color on a light background without careful consideration can exclude users with visual impairments. Designers and developers should avoid using this color for essential text or interactive elements. If the color is crucial for branding, ensure sufficient contrast is achieved through other visual cues or complementary colors.
