Vulcan

#10151A

General Information

The hexadecimal color code #10151A, often referred to as Vulcan, represents a very dark, muted shade that lies within the range of near-black colors. This color is composed of a specific mixture of red, green, and blue (RGB) values, with each component having a low numerical value. Specifically, the RGB values are R: 16, G: 21, and B: 26. In the context of color theory, Vulcan is characterized by its low saturation and brightness, contributing to its somber and understated appearance. It belongs to the family of dark greys and is often perceived as sophisticated and subtle. Due to its darkness, it can be challenging to use effectively in designs requiring high contrast or visibility.

The hex color #10151A, also known as Vulcan, presents significant accessibility challenges due to its dark nature. With very low luminance, it provides insufficient contrast against typical light-colored backgrounds used for text or interactive elements. This poor contrast can make it difficult for users with visual impairments, such as those with low vision or color blindness, to perceive content accurately. Web developers should avoid using this color for text or important user interface elements unless paired with a very light color to ensure a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended to ensure accessibility for a wide range of users. Using color contrast tools to verify the contrast ratio is a crucial step in ensuring an inclusive design. In situations where #10151A is desired for branding or aesthetic purposes, consider using it sparingly and ensuring that critical information is presented with sufficiently contrasting colors.
