The hex color #15111D, a deep, muted shade of purple-gray, presents significant accessibility challenges, especially in text-based applications. Its low luminance value of approximately 2% means it offers very little contrast against equally dark backgrounds, making it difficult for users with visual impairments to read text rendered in this color. To ensure accessibility, it is crucial to pair #15111D with a light background color, such as white or a very pale yellow. This increases the contrast ratio, improving readability for individuals with low vision or color blindness. WCAG guidelines recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using contrast checker tools is highly advisable to confirm compliance. Avoid using #15111D for critical information or interactive elements without sufficient contrast.
