General Information about Ebony (#100A1B)

The hexadecimal color code #100A1B represents a very dark shade of blue-purple, often referred to as Ebony. It's composed of 6.27% red, 3.92% green, and 10.59% blue. In the RGB color space, it's characterized by low values, indicating its darkness. This color resides in the cool spectrum and evokes feelings of sophistication, mystery, and elegance. It's often associated with high-end products and can be used to convey a sense of luxury or exclusivity. Due to its darkness, it is not a commonly used color, but instead, it can be effective as an accent color when paired with brighter, contrasting hues. The color is from the X11 color set, originally developed at MIT in 1987 for the X Window System.

The hex color #100A1B, also known as Ebony, presents significant accessibility challenges, particularly in web design. Its extremely low lightness value (very dark) results in poor contrast when paired with similarly dark colors. According to WCAG guidelines, sufficient contrast between foreground and background elements is crucial for users with visual impairments. Using #100A1B as a background color requires very light text (ideally white or near-white) to meet minimum contrast ratios. Even then, careful evaluation with accessibility tools is necessary to ensure readability. It is advisable to avoid using this color for essential information or interactive elements unless contrast is meticulously addressed. The lack of contrast can also pose problems for users viewing the content on devices with poor screen calibration or in environments with high ambient lighting.
