关于 颜色对比度检查器 - WCAG 2.1可访问性测试
WCAG (Web Content Accessibility Guidelines) require sufficient color contrast between text and background for readability. This Color Contrast Checker calculates the exact contrast ratio between any two colors and checks compliance with WCAG 2.1 Level AA (4.5:1 for normal text, 3:1 for large text) and Level AAA (7:1 normal, 4.5:1 large). Features include: live text preview at multiple sizes, color blindness simulation for Protanopia, Deuteranopia, Tritanopia, and Achromatopsia, and automatic suggestions for accessible color combinations when your current pair fails. Essential for UI/UX designers, front-end developers, and accessibility auditors.
