General Information about Blue Charcoal (#00131A)

The hex color #00131A, also known as Blue Charcoal, is a very dark shade of blue. It belongs to the blue-cyan color family but leans towards a near-black appearance due to its extremely low luminance. In the RGB color model, it is composed of 0% red, 7.45% green, and 10.2% blue. The CMYK color model representation is 100% cyan, 27% magenta, 0% yellow, and 89.8% black. This color is often associated with feelings of sophistication, calmness, and depth. It is commonly used in designs where a subtle and understated aesthetic is desired. Due to its dark nature, it's important to consider accessibility when using this color, ensuring sufficient contrast with text and other elements.

The hex color #00131A, also known as Blue Charcoal, presents significant accessibility challenges, particularly for text-based content. Its extremely low luminance value results in very poor contrast against most common background colors, including white. According to WCAG guidelines, sufficient contrast is essential for readability and usability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Blue Charcoal is highly unlikely to meet these requirements when paired with lighter colors. To improve accessibility, consider using a much lighter color for text or UI elements placed on a #00131A background. Alternatively, use #00131A sparingly, reserving it for purely decorative elements where readability is not critical. Always test color combinations with accessibility tools to ensure compliance with accessibility standards and to meet the needs of all users.
