The color is not part of the standard web-safe color palette and may render slightly differently across various displays and browsers.

The color #21000C, also known as Sepia Black, presents significant accessibility challenges, particularly concerning color contrast. Its extremely dark nature means that text or other elements rendered in this color require very light foreground colors to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A light foreground color such as #FFFFFF or #F0F0F0 is highly recommended. Using this color for large graphical elements or as a background color where contrast is less critical may be more suitable. However, careful consideration and testing with accessibility tools are essential to ensure compliance and usability for all users, including those with visual impairments. Avoid pairing it with any color that has a dark hue. Always test the contrast ratio to ensure it meets accessibility standards.
