के बारे में कलर कंट्रास्ट चेकर WCAG 2.1 - एक्सेसिबिलिटी टेस्ट

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.
