The hex color #170430, also known as Black Rock, presents significant accessibility challenges, particularly in text-based applications. Its very low luminance value of approximately 1.1 cd/m² results in extremely poor contrast against white or light backgrounds. Consequently, foreground text using this color would be nearly unreadable for individuals with normal vision and completely inaccessible to those with low vision or color vision deficiencies. Web Content Accessibility Guidelines (WCAG) require a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text against its background. #170430 fails to meet these criteria by a significant margin with most background colors. To improve accessibility, it is strongly recommended to avoid using #170430 for text or interactive elements. If it is necessary to use this color, ensure that it is paired with a very light background to provide sufficient contrast. Tools like the WebAIM contrast checker can assist in evaluating color pairings.
