Blue Charcoal
General Information about Blue Charcoal
Blue Charcoal, represented by the hexadecimal color code #020718, is a very dark shade of blue. In the RGB color model, it is composed of 0.8% red, 2.7% green, and 9.4% blue. This composition indicates a strong dominance of blue, though the low overall values result in a very dark hue. The color is often associated with feelings of sophistication, mystery, and depth. Due to its dark nature, it is often used to create contrast and highlight lighter elements. In design applications, it is crucial to ensure sufficient contrast with foreground elements to maintain readability and accessibility.
The hex color #020718, also known as Blue Charcoal, presents significant accessibility challenges, particularly in text and user interface design. Its extremely low luminance value (very close to black) results in very poor contrast against typical light backgrounds, such as white or light gray. This can make text illegible and UI elements difficult to distinguish, leading to a poor user experience, especially for individuals with visual impairments. To ensure accessibility, it's essential to avoid using #020718 for text or important interactive elements on light backgrounds. When this color is unavoidable, implement sufficient contrast by pairing it with a very light color. Tools like WebAIM's Contrast Checker can help evaluate and ensure WCAG compliance. Adhering to a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is crucial for ensuring readability and usability for all users.
