It can be used sparingly to add depth and richness to designs, but it should be paired with lighter colors to balance its darkness.

The color #210003, also known as Sepia Black, presents significant accessibility challenges, especially in web design. Its extremely dark nature results in very low contrast against lighter backgrounds, which is essential for readability. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast is crucial for users with visual impairments. Using #210003 for text on a white or light background would likely fail accessibility standards. To improve accessibility, it's recommended to pair this color with much lighter shades to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using this color for crucial UI elements without proper contrast, as it can render them invisible to some users. Using color alone to convey information is also discouraged; always provide text alternatives. Testing with accessibility tools is vital.
