#1A131B

General Information about Vulcan (#1A131B)

The hexadecimal color code #1A131B represents a dark, muted shade of purple, often referred to as Vulcan. It falls within the range of near-black colors, characterized by low saturation and low brightness. In the RGB color model, #1A131B is composed of 10.2% red, 7.45% green, and 10.59% blue. This combination results in a color that is perceived as both sophisticated and somewhat somber. Vulcan's subdued nature makes it a versatile option for backgrounds or accent elements in designs where a subtle, understated feel is desired. However, its low luminance necessitates careful consideration of contrast when used with text or other foreground elements. The color name evokes images of dark stone and volcanic rock, further contributing to its association with strength and solidity.

The color #1A131B, also known as Vulcan, presents significant accessibility challenges, particularly in text and user interface design. Its extremely low luminance value of approximately 0.01 makes it difficult to achieve sufficient contrast against lighter backgrounds, a critical factor for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to ensure readability. Vulcan struggles to meet these ratios when paired with many common background colors. Therefore, when using #1A131B, it's crucial to select very light foreground colors (e.g., shades of white or very light grays) and rigorously test the contrast ratio using accessibility evaluation tools. Consider alternative, lighter shades or incorporating design elements like borders or background shapes to improve contrast and ensure the content is accessible to a broader audience. Failing to address contrast can exclude users with low vision or color deficiencies, severely hindering their ability to interact with the content effectively.
