WCAG 1.4.1 Use of Color requires that color alone cannot convey information - additional visual cues like text, icons, or patterns must supplement color-based indicators. Common violations include form validation errors shown only with red borders, status dots without text labels, and charts using only color differentiation. The guideline benefits users with color blindness, partial sight, and those using monochrome displays. Testing approaches include automated tools for flagging color usage, AI for pattern detection, and manual testing for contextual evaluation, with a combined approach providing the most comprehensive coverage.
