WCAG 1.4.6 Contrast (Enhanced) is a Level AAA accessibility standard requiring higher contrast ratios (7:1 for normal text, 4.5:1 for large text) compared to the basic Level AA requirements. The article explores three testing approaches: automated tools for quick scanning, AI-based testing for complex layouts, and manual testing for nuanced evaluation. Each method has limitations - automated tools miss dynamic content, AI can misinterpret gradients, and manual testing is time-consuming. The most effective strategy combines all three approaches to ensure comprehensive contrast compliance for users with visual impairments.
