In the RGB color model, it is composed of 7.06% red, 8.24% green, and 12.94% blue. Its usage evokes feelings of sophistication, mystery, and formality.

In print design, #121521 can provide a luxurious and high-end feel. The color name 'Vulcan' hints at strength and power, making it suitable for designs that aim to convey these attributes. It should be used deliberately, balancing its intensity with lighter shades for optimal visual impact.

The hex color #121521, also known as Vulcan, presents significant accessibility challenges due to its very dark nature. Its low luminance results in poor contrast against many background colors, especially white or light shades. Text rendered in #121521 on a white background would be difficult to read for users with normal vision and even more so for those with visual impairments. To ensure accessibility, it is crucial to use #121521 sparingly, primarily as a background color paired with very light text or as a subtle accent color. Following WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Tools for contrast checking should be used to confirm compliance. Consideration should be given to providing alternative color schemes to accommodate users with different visual needs.
