💡 Color Conversion & Web Accessibility (WCAG) Guide
1. What is WCAG 2.1 Contrast Ratio?
The Web Content Accessibility Guidelines (WCAG) dictate minimum contrast ratios between text and backgrounds to ensure readability for users with visual impairments or color blindness.
2. AA vs AAA Compliance
Level AA is the standard legal requirement for most commercial websites (minimum 4.5:1 for body text). Level AAA is the highest accessible standard (minimum 7.0:1).
3. Color Spaces Explained
RGB and HEX are additive digital screen formats, HSL is intuitive for human color harmonies (Hue, Saturation, Lightness), and CMYK is standard for physical print design.
