Its somber tone makes it suitable for designs that require a sense of depth, mystery, or sophistication. The color is part of the dark violet color range. Because the color is very dark, it is not often used as a main color on websites or in prints. The color can be used to create a shadowy effect.

The hex color #181023, also known as Vulcan, presents significant accessibility challenges, especially when used for text or interactive elements. Its extremely low luminance value results in very poor contrast against typical light backgrounds, making it difficult for users with visual impairments to discern content. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Vulcan falls far short of these requirements against a white background, potentially excluding users with low vision or color blindness. To improve accessibility, consider pairing Vulcan with much lighter colors or using it sparingly for purely decorative purposes. Ensure sufficient contrast by using contrast checking tools and adhering to accessibility standards to provide an inclusive experience for all users. Adding a white or light-colored outline around text in Vulcan can also increase readability. Furthermore, avoid using this color to convey important information without any other visual cues.
