General Information about #100B1C (Ebony)

The hex color #100B1C, commonly known as Ebony, is a very dark shade of gray-black with a hint of purple. It belongs to the family of dark colors, evoking a sense of sophistication and mystery. In the RGB color model, #100B1C consists of 6.27% red, 4.31% green, and 11.0% blue. In the CMYK color model, if used for printing, it is composed of 43% cyan, 61% magenta, 0% yellow, and 89% black. This hex color is frequently used in graphic design, web development, and fashion to create a sense of depth, elegance, or somberness. Its subtle purplish undertone sets it apart from pure black, making it a compelling choice for projects that need a touch of uniqueness and refinement. The color has a very low lightness, which makes it hard to use in contexts with text.

The hex color #100B1C, also known as Ebony, presents significant accessibility challenges, especially in text-based applications. Its extremely dark nature results in very low contrast against typical light backgrounds, potentially violating WCAG (Web Content Accessibility Guidelines) standards. To ensure readability and usability for individuals with visual impairments, it is crucial to avoid using #100B1C for text or essential graphical elements on light backgrounds. If this color is unavoidable, a very light color such as #FFFFFF or #FAF9F6 must be used as a foreground. It should be tested with tools that measure color contrast ratios to confirm it meets the minimum required contrast ratio of 4.5:1 for normal text and 3:1 for large text. Using color combinations with this hex require careful consideration and testing to guarantee a positive user experience for people of all abilities. Moreover, it should be accompanied by alternative cues (e.g. visual cues, labels or symbols) to convey important information.
