Asphalt

#180312

General Information about Asphalt

The hex color #180312, often referred to as Asphalt, is a very dark, desaturated shade of purple. In the RGB color model, it is composed of 9.41% red, 1.18% green, and 7.06% blue. This composition results in a very low luminance value, making it appear nearly black. The color is associated with themes such as darkness, sophistication, and mystery. It's frequently used in designs aiming for a modern or industrial aesthetic. Due to its darkness, it's crucial to pair it with lighter colors to provide sufficient contrast for readability and visual interest. Its low saturation also contributes to a muted, subtle feel, making it suitable for backgrounds and accents where a bold statement is not desired.

The color #180312, also known as Asphalt, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance value means that it offers very little contrast against both white and light-colored backgrounds. This poses readability issues for users with visual impairments, including those with low vision or color blindness. The Web Content Accessibility Guidelines (WCAG) emphasize a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text to ensure readability. Asphalt fails to meet these contrast standards with typical foreground colors. To improve accessibility, consider using much lighter text colors such as whites and very light grays, or using Asphalt sparingly for purely decorative elements where readability isn't critical. Testing with accessibility tools is highly recommended to validate compliance.
