General Information about Vulcan (#121523)

The hex color code #121523, often referred to as 'Vulcan', is a deep, dark shade of blue-black, residing in the lower ranges of the color spectrum due to its low RGB values. Composed of 7.1% red, 8.2% green, and 13.7% blue, it reflects minimal light, resulting in a subdued and somewhat mysterious appearance. In the RGB color model, it's represented as rgb(18, 21, 35). When converted to the CMYK color model, it translates to 49% cyan, 40% magenta, 0% yellow, and 86% black. This hex color is frequently employed in contexts where a sense of depth, sophistication, or understated elegance is desired. Because of its dark nature, it is rarely used as the primary color on larger surface areas. It is suitable for text in combination with white background in limited occurences.

The hex color #121523, also known as Vulcan, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of approximately 0.007 results in very poor contrast against standard white text or backgrounds. This makes it difficult for individuals with low vision to discern text or graphical elements. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. #121523 fails to meet these criteria in almost every common use case. To improve accessibility, it is crucial to pair this color with very light shades, use it sparingly for decorative purposes only, or increase the text size significantly when used for textual content. Also avoid using #121523 for crucial interface elements.
