HEX vs RGB vs HSL

  • ✓HEX (#RRGGBB) is the compact 6-character hexadecimal format standard in web development.
  • ✓RGB defines colors through Red, Green, and Blue light intensities from 0 to 255.
  • ✓HSL represents Hue (angle 0–360°), Saturation (0–100%), and Lightness (0–100%), making it the most intuitive format for humans to adjust.
