The hex color #181321, often referred to as "Vulcan," is a very dark, muted shade of purple tending towards black. It belongs to the family of near-black colors and evokes a sense of mystery, sophistication, and depth. In color theory, such dark hues are generally considered neutral and are often used as background colors or to provide contrast to brighter elements. Its RGB values are R:24, G:19, B:33, indicating a higher blue component which gives it the purple undertone.

The darkness of the color means that it is best used with lighter colors for text and other visual elements.

The hex color #181321, also known as Vulcan, presents significant accessibility challenges due to its low luminance. With such a dark shade, it's imperative to use light text colors to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. When using #181321 as a background, consider pairing it with colors like white (#FFFFFF) or light yellows (#FFFFE0) to meet these contrast requirements. Ensure that all interactive elements, such as buttons and links, also have clear visual indicators and sufficient contrast to be easily identifiable by users with visual impairments. Regularly testing color combinations with accessibility tools is crucial to maintain an inclusive user experience.
