The color #221F18, also known as Oil, presents significant accessibility challenges, especially in web design. Its very dark hue results in extremely low contrast against lighter backgrounds, potentially making text and other elements unreadable for users with visual impairments.

Careful evaluation and testing are essential to ensure compliance with accessibility standards.
