#040716

General Information about Blue Charcoal (#040716)

The hex color #040716, also known as Blue Charcoal, is a very dark shade of blue, almost appearing black to the naked eye. It belongs to the family of blue colors but leans heavily towards the darker end of the spectrum. This color is frequently used in design contexts where a sense of sophistication, depth, or mystery is desired. Due to its low luminance value, #040716 is not ideal for text or elements requiring high visibility unless paired with a very light contrasting color. Its primary attributes include a subtle blue undertone which distinguishes it from true black, offering a slightly softer and more nuanced aesthetic. It's often found in branding, web design, and interior decorating where a muted, elegant palette is preferred.

The hex color #040716, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. Its very dark nature results in poor contrast against lighter backgrounds, which is crucial for readability and usability, especially for users with visual impairments. Web Content Accessibility Guidelines (WCAG) emphasize a contrast ratio of at least 4.5:1 for standard text and 3:1 for large text against its background to meet AA compliance. Given the darkness of #040716, achieving acceptable contrast ratios requires very light text colors, and even then, careful testing is necessary. Designers should prioritize sufficient contrast to ensure content is accessible to all users, including those with low vision or color blindness. Consider alternative, lighter shades or combinations with brighter accent colors to enhance overall accessibility and user experience. Testing with accessibility tools is highly recommended.
