#001115

General Information

The hexadecimal color code #001115 represents a very dark shade of blue, often described as Blue Charcoal. It is composed of 0% red, 6.67% green, and 8.24% blue. In the RGB color space, it is nearly black, possessing minimal luminance. This color is frequently associated with feelings of sophistication, depth, and calmness. Due to its low brightness, it is best used as an accent color or background element rather than for text, where readability is paramount. Its subtle blue undertones distinguish it from pure black, offering a softer and more nuanced aesthetic. This makes it suitable for creating a sense of understated elegance in various design applications.

The color #001115, also known as Blue Charcoal, presents significant accessibility challenges due to its very low luminance. This dark shade provides insufficient contrast against white backgrounds, potentially making text and interactive elements unreadable for users with visual impairments. To ensure accessibility, it is crucial to avoid using #001115 for text or important UI elements unless paired with a very light color that provides a contrast ratio meeting WCAG guidelines (minimum 4.5:1 for normal text and 3:1 for large text). Consider using tools to check color contrast and adjust color pairings accordingly. When using this color as a background, ensure that all foreground elements have sufficient contrast. Providing alternative high-contrast themes can further enhance accessibility for all users.
