General Information about Vulcan (#181222)

The hexadecimal color code #181222, also known as Vulcan, represents a very dark shade of purple-blue. In the RGB color model, it is composed of 9.41% red, 7.06% green, and 13.33% blue. This color is often associated with seriousness, sophistication, and a sense of mystery. Due to its low brightness and saturation, it tends to create a calm and reserved impression. Vulcan can be used effectively in various design contexts to convey elegance and a subtle sense of power. It is commonly found in branding materials, web design, and even interior design to create a modern, refined look. However, care should be taken to ensure sufficient contrast with other elements to maintain readability and accessibility.

The color #181222, also known as Vulcan, presents accessibility challenges due to its dark nature. Its low luminance results in poor contrast against lighter backgrounds, which is problematic for users with visual impairments. To ensure web content is accessible, it is crucial to use Vulcan sparingly, especially for text or interactive elements. When used, pair it with very light colors like white or pale yellow to meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended to ensure readability for users with low vision. Also, avoid using this color as the sole indicator of functionality, such as in hyperlinks; instead, provide additional cues like underlines or icons to ensure usability for all users, including those who are colorblind.
