Asphalt

#180D05

General Information

The hex color code #180D05 represents a very dark shade of brown, often described as asphalt. In the RGB color model, it consists of 9.41% red, 5.1% green, and 1.96% blue. This means it's primarily composed of red, with significantly lower levels of green and blue. The color's darkness is due to the low overall values across all three color channels. In the HSL (hue, saturation, lightness) system, it has a hue angle of 25 degrees, a saturation of 65.5%, and a lightness of 5.7%. This indicates a hue leaning towards orange-brown, a high level of color intensity (though perceived as muted due to the darkness), and extremely low brightness, which explains its dark appearance. Colors like #180D05 are often used to create a sense of depth, sophistication, or industrial style in design.

The hex color #180D05, a very dark, desaturated shade, presents significant accessibility challenges. Its extremely low luminance makes it unsuitable as a primary text color on white or light backgrounds, as the contrast ratio would be far below the WCAG recommended levels for readability. For body text, a contrast ratio of at least 4.5:1 is recommended, while large text requires a minimum of 3:1. #180D05 will likely fail both tests against standard backgrounds. When used for interactive elements like buttons or links, the lack of contrast could make it difficult for users, especially those with visual impairments, to identify and interact with them. Therefore, if this color is used, it's crucial to pair it with very light colors for text or interactive elements to ensure accessibility. Thoroughly test the color combination using accessibility checkers to confirm compliance with WCAG guidelines.
