Sepia Black

#28000B

General Information about #28000B

The hexadecimal color #28000B, also known as Sepia Black, is a very dark, muted shade of red-brown. In the RGB color model, it is composed of 16.08% red, 0% green, and 4.31% blue. This combination of low RGB values results in its dark appearance. The color is commonly associated with feelings of seriousness, antiquity, and earthiness. The lack of green, together with a small amount of blue, shifts the color more to the brown and red spectrum. It is not commonly used in mainstream design due to its darkness and potential accessibility issues; however, it can be effective as an accent color or for specific thematic purposes to portray richness and grounding.

The color #28000B, a deep, muted red-brown, presents significant accessibility challenges, especially when used as a foreground color on a white background. Its extremely low lightness value results in a very poor contrast ratio, failing to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (AA) or large text (AAA). This means that users with visual impairments, including those with low vision or color blindness, would struggle to read text displayed in this color. To improve accessibility, it is strongly recommended to avoid using #28000B for text or interactive elements unless paired with a very light background. A lighter shade from the white spectrum would be more appropriate. Tools like contrast checkers can accurately assess the contrast ratio and suggest alternative, more accessible color combinations. It is also crucial to consider users with cognitive disabilities who may benefit from high contrast.
