The hex color code #131521, often referred to as "Vulcan", is a very dark, desaturated shade of blue-gray.

In the RGB color model, #131521 consists of 7.45% red, 8.24% green, and 12.94% blue. This color has a low saturation level, which contributes to its muted appearance.

The hex color #131521, also known as Vulcan, presents significant accessibility challenges, especially for users with visual impairments. Its extremely low luminance value necessitates careful consideration of color contrast when used for text or interactive elements. According to WCAG guidelines, sufficient contrast between foreground and background colors is crucial for readability. To ensure accessibility, it is imperative to pair #131521 with very light colors (such as white or shades of yellow) that provide a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Tools like contrast checkers can help determine if the contrast ratio meets accessibility standards. Avoid using this color for critical information or interactive elements without ensuring adequate contrast, as it can exclude users with low vision or color blindness. For decorative purposes, this requirement is slightly relaxed, but caution is still advised.
