General Information about #171D1D

The hex color #171D1D, sometimes referred to as "Aztec", is a very dark shade of gray, almost bordering on black. In the RGB color model, it's composed of 9.02% red, 11.37% green, and 11.37% blue. Its primary characteristic is its low luminance, making it a challenging color to work with in terms of accessibility and contrast. Colors close to black such as this one are often used to convey a sense of sophistication, mystery, or solidity. In web design and graphic design, it can be useful for creating a dark, modern aesthetic, but care must be taken to ensure readability. It's more common to use lighter elements on top of this color than the other way around. The color is mainly used as a decorative color, rarely as a central color.

The hex color #171D1D, often referred to as "Aztec", presents significant accessibility challenges due to its very low luminance. Its dark nature results in poor contrast against typical light backgrounds (such as white), making it difficult for users with visual impairments to discern text or interface elements using this color. Web Content Accessibility Guidelines (WCAG) emphasize a minimum contrast ratio of 4.5:1 for standard text and 3:1 for large text against its background to ensure readability. #171D1D falls far short of these recommendations when paired with most background colors. To improve accessibility, consider using a much lighter foreground color or a significantly lighter shade as the background when employing #171D1D. Tools like contrast checkers can help determine if a specific color combination meets accessibility standards. Also, avoid using this color for critical interactive elements without clear visual cues.
