Sepia Black

#25000D

General Information about #25000D

The hexadecimal color code #25000D, often referred to as Sepia Black, represents a very dark and muted shade of red. It is composed of 14.5% red, 0% green, and 5.1% blue. In the RGB color space, this translates to values of R:37, G:0, and B:13. The color's subdued nature is primarily due to the low values across all color channels, particularly the absence of green. This color is not commonly found in nature but evokes a sense of vintage photography and aged documents, hence the association with "sepia". Due to its darkness, it absorbs a significant amount of light and may appear almost black in certain lighting conditions. In the HSV/HSB color space, it has a hue of 339 degrees, a saturation of 100%, and a brightness of 14.5%.

The hex color #25000D, also known as Sepia Black, presents significant accessibility challenges, particularly in web design. Its extremely low luminance results in very poor contrast against typical background colors like white. This makes text or graphical elements using this color difficult to read for users with visual impairments, including those with low vision, color blindness, or general visual fatigue. According to WCAG guidelines, sufficient contrast is crucial for ensuring content is perceivable. To improve accessibility, consider using #25000D sparingly, perhaps as a subtle accent, and always pair it with a very light background color to meet minimum contrast ratios. A contrast checker tool can help ensure compliance with accessibility standards. Avoid using this color for essential information, interactive elements, or large blocks of text.
