It is composed of 8.24% red, 6.67% green, and 10.2% blue. In the RGB color space, it represents a low intensity across all channels, resulting in its dark appearance. This color is frequently used in graphic design and web development where a dark, sophisticated, or mysterious aesthetic is desired.

The color finds applications in backgrounds, accents, and other visual elements where subtlety and depth are required.

The hex color #15111A, also known as Vulcan, presents significant accessibility challenges, particularly in text-based applications. Due to its very dark nature, it provides insufficient contrast against similarly dark backgrounds, making text illegible for users with visual impairments. To ensure accessibility, it is crucial to pair Vulcan with significantly lighter colors for text or interactive elements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Using online contrast checkers can help verify compliance. Additionally, avoid using Vulcan for essential visual cues without providing alternative indicators, such as labels or icons, to accommodate users with color blindness. Thoughtful color selection is paramount to creating inclusive and accessible digital experiences.
