Its darkness results in a low luminance value. Blue Charcoal evokes a sense of sophistication and depth. It's a color often associated with professionalism, calmness, and elegance.

The color has a certain timeless appeal and is a staple in numerous design palettes.

The hex color #01111A, also known as Blue Charcoal, presents significant accessibility challenges, especially in text-based applications. Its extremely low luminance value means that it requires very light text colors to meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. Using a text color like white (#FFFFFF) is essential to provide sufficient contrast for readability. Without adequate contrast, users with visual impairments, including those with low vision or color blindness, will struggle to perceive the text. When using this color for backgrounds, careful consideration must be given to ensuring that all interactive elements such as buttons and links also meet the contrast standards. Providing alternative high-contrast themes or allowing users to adjust color settings can improve the accessibility of content using #01111A. Also, avoid using this color for essential information that needs to stand out. Always test color combinations with accessibility tools to confirm compliance.
