General Information about Sepia Black

The hexadecimal color code #280403, often referred to as Sepia Black, is a dark and muted shade of reddish-brown. It is composed of 15.7% red, 1.6% green, and 1.2% blue. In the RGB color model, this translates to R:40, G:4, B:3. The color is very dark, characterized by its low saturation and luminance values. It tends to evoke feelings of warmth, antiquity, and earthiness. Sepia Black resides in the dark end of the color spectrum, making it suitable for creating subtle contrasts when paired with lighter shades. Its closest web-safe color equivalent might be a darkened shade of brown or burgundy. The absence of vibrant hues gives it a timeless and understated quality, which helps designers to apply this tone to create a classic aesthetic.

The color #280403, also known as Sepia Black, presents significant accessibility challenges, particularly in web design. Its extremely low luminance (darkness) results in very poor contrast against typical light backgrounds. This makes it difficult for users with visual impairments, such as those with low vision or color blindness, to distinguish text or graphical elements rendered in this color. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast ratios are crucial for readability and usability. Using #280403 for text or important interface elements would likely fail to meet the minimum contrast requirements, potentially excluding a significant portion of users. Therefore, it is vital to pair this color with a very light color or avoid it altogether in scenarios where accessibility is a priority. Providing alternative high-contrast themes or options is also highly recommended when incorporating such a dark shade.
