General Information about Sepia Black

The hex color code #210004, also known as Sepia Black, is a very dark shade of red. It resides in the red color spectrum but possesses a muted, almost brownish quality, reminiscent of aged photographs or antique documents, which is why it's referred to as "Sepia." In the RGB (Red, Green, Blue) color model, it's composed of 13% red, 0% green, and 2% blue. In the CMYK (Cyan, Magenta, Yellow, Black) color model, it consists of 0% cyan, 100% magenta, 69% yellow, and 87% black. Due to its high black component, it reflects very little light, resulting in a low luminance value. This color is more commonly used for backgrounds than foregrounds.

The color #210004, also known as Sepia Black, presents significant accessibility challenges, particularly concerning color contrast. With its very dark hue, it requires extremely light text or foreground elements to meet WCAG (Web Content Accessibility Guidelines) standards for readability. Using white text on a background of #210004 would improve contrast, but careful consideration is necessary. Ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) to comply with AA standards. Insufficient contrast can exclude users with low vision or color blindness. Additionally, avoid using #210004 as the sole indicator for interactive elements; supplement it with labels or other visual cues to aid users with cognitive disabilities. Thoroughly testing with accessibility tools is crucial to guarantee usability for all users.
