General Information about Vulcan (#17191E)

#17191E, also known as Vulcan, is a deep, dark shade of gray that evokes feelings of sophistication, mystery, and understated elegance. It belongs to the family of achromatic colors, meaning it lacks strong hue or saturation. This neutral characteristic makes it a versatile color that can be easily integrated into various design projects. In the RGB color model, #17191E consists of 9.02% red, 9.8% green, and 11.76% blue. Its low lightness value contributes to its dark appearance. In color psychology, dark grays are often associated with formality, professionalism, and a sense of stability. However, it's essential to use this color thoughtfully, as overuse can sometimes create a somber or oppressive atmosphere. #17191E is frequently used in modern web design and graphic design to create sleek and minimalist layouts.

The hex color #17191E, also known as Vulcan, presents significant accessibility challenges, especially for users with visual impairments. Its very low luminance value results in a poor contrast ratio against standard white backgrounds, making text or interface elements using this color difficult to read. To ensure inclusivity, it's crucial to pair #17191E with significantly lighter colors that provide sufficient contrast (WCAG 2.0 requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text). When using #17191E, avoid placing important information or interactive elements relying solely on color to convey meaning. Additionally, providing alternative text descriptions for images or icons using this color is essential. Consider offering users the option to switch to a high-contrast theme to improve usability for those with visual impairments. Thoroughly test color combinations with accessibility evaluation tools to identify and address potential issues.
