WCAG 1.4.11 Non-text Contrast requires UI components and informative graphics to maintain at least a 3:1 contrast ratio against adjacent colors. The guide explores three testing approaches: automated tools excel at quickly identifying common contrast issues but struggle with complex visuals and context; AI-powered testing can process large amounts of visual content but may miss purpose and context; manual testing provides real-world usability evaluation and catches nuanced issues but can be time-consuming and subjective. The most effective strategy combines all three methods, starting with automated tools for broad coverage and following up with manual testing for thorough evaluation.
