Basic Color Numbering

• Numbers range from #1 to #60
• Higher numbers = Lighter colors
• Lower numbers = Darker colors
  • #1 is the darkest shade
  • #60 is the lightest shade

Gray Hair Blending System

The color code for gray-blended shades uses a two-part numbering system:

• First digit: Base color level
• Last two digits: Percentage of gray hair

Examples:

• #210: Dark brown (level 2) with 10% gray hair
• #220: Dark brown (level 2) with 20% gray hair
• #330: Medium brown (level 3) with 30% gray hair

"R" Modifier System

The letter "R" indicates a lighter variation of the base color:

• When "R" follows a number, it means one shade lighter than the base
• Example: 4R = Medium brown (level 4) lightened by one shade
