General Information about #2A0104

The hexadecimal color code #2A0104 represents a very dark shade of red, often described as Sepia Black. It is composed of 16.47% red, 0.39% green, and 1.57% blue. In the RGB color model, these values translate to 42 red, 1 green, and 4 blue. The color's low saturation and luminance contribute to its muted, almost black appearance. Colors like this are often used to create a sense of depth, mystery, or understated elegance. In terms of its spectral properties, #2A0104 absorbs most wavelengths of light, reflecting only a small amount of red, resulting in its characteristic dark hue. It's commonly associated with themes of antiquity, sophistication, or subtle luxury.

The color #2A0104, a deep shade of sepia black, presents significant accessibility challenges. Its low luminance value (very dark) results in extremely poor contrast against both white and most light-colored backgrounds. This lack of contrast makes text and other visual elements difficult or impossible to read for users with visual impairments, including those with low vision or color blindness. To ensure accessibility, it's crucial to avoid using this color for text, icons, or interactive elements without employing a very light background color to provide sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. For WCAG AAA compliance, even higher contrast ratios are needed. Therefore, #2A0104 should be used sparingly and primarily for decorative purposes where accessibility is not a primary concern, or paired carefully with high contrast colors.
