About Blue Charcoal (#000E13)

The hex color #000E13, also known as Blue Charcoal, is a very dark shade of blue. It belongs to the blue color family, but its deep tone gives it a near-black appearance. In the RGB color model, it is composed of 0% red, 5.5% green, and 7.5% blue. This results in a color that is very low in saturation and luminance. The perceived darkness of #000E13 makes it suitable for creating backgrounds or subtle accents where a deep, muted tone is desired. However, due to its low luminance, it should be used with caution, particularly in contexts where readability and contrast are crucial. When designing with this color, it is imperative to pair it with lighter shades to ensure sufficient visual contrast and accessibility.

The hex color #000E13, also known as Blue Charcoal, presents significant accessibility challenges, particularly in text-based contexts. Its extremely low luminance value (very dark) results in poor contrast against most background colors. According to WCAG guidelines, sufficient contrast is crucial for readability and usability, especially for users with visual impairments. A color like #000E13 demands very light foreground colors to achieve acceptable contrast ratios (ideally 4.5:1 for normal text and 3:1 for large text). Designers and developers should carefully evaluate color pairings and consider providing alternative high-contrast themes or allowing users to customize color schemes. When using #000E13, ensure that interactive elements such as buttons and links are clearly distinguishable through visual cues beyond color alone. Textures, icons, or borders can greatly improve accessibility. Thorough accessibility testing with assistive technologies and diverse user groups is essential to identify and address potential barriers.
