The hex color #15191F, also known as Vulcan, presents significant accessibility challenges. Its low luminance value of approximately 2% results in poor contrast against standard white backgrounds. This lack of contrast makes it difficult for users with visual impairments, including those with low vision or color blindness, to discern text or important interface elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Vulcan falls far short of these recommendations, potentially excluding a significant portion of users. To improve accessibility, it is crucial to pair #15191F with much lighter colors, ensuring sufficient contrast. Alternatively, consider using a different, more accessible color palette altogether.
