General Information about Blue Charcoal

The hex color #011019, also recognized as Blue Charcoal, is a very dark shade of blue, almost approaching black. It is composed of 0.4% red, 6.3% green, and 9.8% blue. In the RGB color space, it is represented as RGB(1, 16, 25). Blue Charcoal conveys a sense of depth, mystery, and sophistication. Due to its muted nature, it is often associated with calmness and stability. Its subtle blue undertones differentiate it from pure black, adding a layer of complexity and visual interest. In color psychology, dark blues are often linked to trust, loyalty, and intelligence. Because of its depth, this color should be used carefully and sparingly.

The hex color #011019, also known as Blue Charcoal, presents significant accessibility challenges due to its very dark nature. With extremely low luminance, it provides insufficient contrast against lighter backgrounds, making it difficult for individuals with visual impairments to discern text or interface elements. Web developers should avoid using this color as a primary text or foreground color unless paired with a very light background color that provides a contrast ratio meeting WCAG guidelines (ideally 4.5:1 for normal text and 3:1 for large text). Using tools to check color contrast is essential. Consider also that individuals with color blindness may struggle to differentiate #011019 from other dark shades. Therefore, relying solely on color to convey information should be avoided, and alternative visual cues should be provided.
