Due to its darkness, it's crucial to consider accessibility guidelines when using this color, especially in contexts involving text or interactive elements.

The hex color #170021, often referred to as Black Russian, presents significant accessibility challenges, especially in text-based applications. Its extremely low luminance value of approximately 0.008 makes it nearly indistinguishable from true black. Consequently, using #170021 as a text color against a dark background (or vice versa) results in abysmal contrast ratios, failing to meet WCAG (Web Content Accessibility Guidelines) standards for readability. To ensure accessibility, it's crucial to avoid using this color for text or interactive elements without employing a very light or bright contrasting color. A minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text is recommended. Using tools to verify contrast ratios is highly advised when incorporating such dark hues in design to avoid accessibility barriers for users with visual impairments. Consider using this color sparingly for purely decorative elements where readability is not a primary concern.
