General Information about Blue Charcoal

The hex color code #00071E, also known as Blue Charcoal, is a very dark shade of blue, almost appearing black. It is composed of 0% red, 2.7% green, and 11.8% blue. In the RGB color model, it is represented as (0, 7, 30). This color is often associated with feelings of sophistication, mystery, and elegance. Due to its dark nature, it is frequently used as a background color or in designs where a subtle, understated look is desired. However, its low luminance value presents challenges in terms of accessibility, requiring careful consideration of contrast ratios to ensure readability when used with text or other graphical elements.

The hex code #00071E, a very dark blue, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance means that text or graphical elements using this color as a background or foreground will have very poor contrast against most other colors. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast is crucial for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Given its near-black nature, #00071E will likely fail these contrast tests against lighter colors, making content difficult or impossible to perceive. Therefore, when using #00071E, it's imperative to pair it with very light colors, such as white or light yellow, and rigorously test the contrast ratio to ensure compliance with accessibility standards. Providing alternative high-contrast themes is also beneficial.
