From a technical perspective, #221F1A has a hue angle of 36 degrees, a saturation of 13.3%, and a lightness of 11.8%. It is generally used in design applications where a dark, unobtrusive background or accent color is needed, but it requires careful consideration due to its potential impact on readability and accessibility. The color is more popular in industrial design.

The hex color #221f1a, often referred to as 'Oil,' presents significant accessibility challenges. Its extremely low luminance value means that text rendered in this color against a white or light-colored background will likely fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. Specifically, it falls far short of the minimum 4.5:1 contrast ratio needed for normal text and 3:1 for large text, as outlined in WCAG AA. Consequently, users with visual impairments, including those with low vision or color blindness, will struggle to read the content. To ensure inclusivity, web developers should avoid using #221f1a for text or interactive elements unless paired with a very light background color that provides sufficient contrast. Tools are available to check the contrast ratio of color combinations to confirm compliance with accessibility standards. Furthermore, consider providing alternative color themes that offer better contrast for users who need them.
