General Information about Sepia Black

The color #300904, also known as Sepia Black, is a dark and muted shade of brown. It resides within the reddish-brown color family, characterized by its desaturated nature and low luminance. In the RGB color model, it is composed of 18.82% red, 3.53% green, and 1.57% blue. Its CMYK values are approximately 0% cyan, 81% magenta, 92% yellow, and 81% black. This color evokes a sense of antiquity, warmth, and sophistication. Due to its dark nature, it is often used sparingly or as an accent color. The name 'Sepia Black' is reminiscent of sepia-toned photographs, which have a warm, brownish hue associated with vintage or aged images. It shares some similarities with colors like umber and dark sienna.

The color #300904, also known as Sepia Black, presents significant accessibility challenges, particularly in web design. Its extremely low luminance value of 1.06 cd/m² results in a very poor contrast ratio against standard white backgrounds (e.g., #FFFFFF). According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Sepia Black falls far short of these recommendations, making it difficult for many users to read text or distinguish elements. To improve accessibility, avoid using #300904 for text or interactive elements on light backgrounds. If it must be used, pair it with a very light color to achieve an acceptable contrast ratio. Tools such as contrast checkers can help assess and adjust color combinations to meet accessibility standards.
