#180B1B

General Information about #180B1B

The hexadecimal color code #180B1B, also known as Vulcan, represents a very dark, muted shade of purple, almost appearing as a dark gray or black. It resides within the range of colors with extremely low luminance values, making it a challenging color to work with in terms of accessibility and visibility. This color evokes a sense of depth, mystery, and sophistication. In the RGB color model, #180B1B is composed of 9.41% red, 4.31% green, and 10.59% blue. Its presence is mostly felt in design realms requiring elegance and subtle touches, but its limited brightness necessitates careful consideration of contrast and appropriate color pairings to ensure visual clarity and user-friendliness.

The color #180B1B, also known as Vulcan, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance value (very dark) results in poor contrast against most background colors, including white. This lack of contrast can make it difficult for individuals with visual impairments, such as low vision or color blindness, to read text or distinguish elements using this color. Web Content Accessibility Guidelines (WCAG) emphasize a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Vulcan is highly unlikely to meet these guidelines unless paired with a very light color. Designers should carefully consider the impact on users with disabilities and prioritize sufficient contrast when using this color. Using color contrast checker tools is highly recommended to test the accessibility of color combinations involving #180B1B. Avoid using this color for essential information without ensuring adequate contrast.
