General Information about #001117

The hex color #001117, often referred to as Blue Charcoal, is a very dark shade of blue that leans towards black. In the RGB color model, it is composed of 0% red, 6.67% green, and 9.02% blue. This composition results in a color with a subtle blue undertone, giving it a sophisticated and muted appearance. The color is often associated with calmness, stability, and sophistication. It can be found in various applications, ranging from digital interfaces to physical products, where a dark, understated color is desired. In terms of color theory, #001117 is considered a low-saturation color, making it suitable as a background or accent color in design projects.

The hex color #001117, also known as Blue Charcoal, presents significant accessibility challenges due to its very low luminance. With such a dark shade, ensuring sufficient contrast with foreground text or interactive elements is crucial. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text (14pt bold or 18pt regular). Using white text (#FFFFFF) on a #001117 background yields a low contrast ratio, failing accessibility standards. Therefore, it's imperative to use a much lighter color, or even pure white, to ensure readability for users with visual impairments. Careful consideration must also be given to focus indicators on interactive elements, ensuring they are clearly visible against this dark background. The color is not suitable for key information if not paired with very bright color, as it would be missed by people with low visability.
