The hexadecimal color code #17191B, often referred to as "Vulcan", represents a very dark, almost black shade. In the RGB color model, it is composed of 9.02% red, 9.8% green, and 10.59% blue. In the CMYK color model, it consists of 15% cyan, 7% magenta, 0% yellow, and 89% black. This color resides within the range of very low luminance values, indicating its extreme darkness.

Due to its near-black nature, #17191B is most effectively used as a background color or in combination with significantly lighter colors to provide sufficient contrast.
The hex color #17191B, also known as Vulcan, presents significant accessibility challenges. Its extremely low luminance value of 0.009 makes it difficult to distinguish from pure black, severely impacting readability for users with visual impairments or those viewing the content on low-contrast screens. According to WCAG guidelines, this color fails all contrast ratio tests against white (#FFFFFF) and even light grays. To ensure accessibility, it's crucial to avoid using #17191B for text or interactive elements. If this dark hue is essential for design aesthetics, consider pairing it with extremely light colors to achieve an acceptable contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Furthermore, providing alternative visual cues, such as underlines for links or icons for interactive elements, can enhance usability for all users.
