#181102

General Information about #181102

The hexadecimal color code #181102 represents a very dark shade of brown, often referred to as 'Acadia' in color naming systems. It is composed of 9.41% red, 6.67% green, and 0.78% blue. In the RGB color model, these values translate to a very low overall luminance, resulting in a color that appears almost black. This color evokes feelings of earthiness, warmth, and stability, although its darkness can also suggest seriousness or austerity. Its muted nature makes it suitable for applications where subtlety and understated elegance are desired. However, caution is advised when using it in contexts where visibility is paramount, especially in text-based applications. Dark brown colors like Acadia have historical and cultural associations with nature, wood, and traditional craftsmanship.

The color #181102, a very dark shade of brown, presents significant accessibility challenges, especially in text-based applications. Its extremely low luminance (approximately 1.5%) results in very poor contrast against standard white backgrounds. This lack of contrast makes it difficult for users with visual impairments, including those with low vision or color blindness, to distinguish text rendered in this color. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. #181102 fails to meet these standards against almost any light background. To improve accessibility, it's crucial to pair this color with very light shades. Implementing accessibility checks during the design phase is essential to ensure content is usable by everyone.
