General Information about #131820

The color #131820, also known as Vulcan, is a very dark, muted shade of blue-gray, belonging to the dark side of the color spectrum. It is composed of 7.45% red, 9.41% green, and 12.55% blue. In the RGB color space, it represents low intensity across all three primary colors, contributing to its dark and understated appearance. This hex code is often associated with feelings of sophistication, stability, and seriousness. Vulcan can often appear almost black. Its subtle blue undertones provide a depth that distinguishes it from pure black, making it a versatile choice for various design applications where a refined and muted color is desired. This color is not often found in nature.

The hex color #131820, also known as Vulcan, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value results in a poor contrast ratio against lighter backgrounds, making text and interactive elements difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Vulcan often fails to meet these criteria when paired with common background colors like white or light gray. Web developers should avoid using #131820 for text or important UI elements unless paired with a very light color that ensures sufficient contrast. Tools like contrast checkers can help verify compliance. Alternatives to consider include brighter shades or the use of sufficient contrast by adding a white or very bright text color.
