The color #18101C, also known as Vulcan, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of 3.5 cd/m² results in very poor contrast against standard white backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Vulcan fails to meet these criteria, making text rendered in this color difficult to read. To improve accessibility, it is recommended to use Vulcan sparingly for purely decorative elements or to pair it with very light text colors, ensuring a sufficient contrast ratio. Tools like contrast checkers can help verify compliance with accessibility standards. Alternatives should be considered where legibility is crucial.
