WCAG Color Contrast Guidelines

Web Content Accessibility Guidelines (WCAG) 2.0 requires minimum contrast ratios for text to ensure readability by individuals with moderate visual impairments. Normal text is defined as text under 18pt (24px) or 14pt (19px) bold. Large text is defined as 18pt (24px) or larger, or 14pt (19px) or larger bold. AA rating represents standard legal compliance, while AAA rating denotes enhanced accessibility (often required for government or public sector portals).
