HOW DO WE NAME THE HAIR COLORS?

Generally speaking, the bigger the color code is, the lighter the color will be. E.g. #20 color is lighter than #18 color. #1 color is the darkest while #60 is the lightest.

For gray colors, the last two digits of the color code refer to how much percentage of gray hair is blended in. For example, in color #210, #2 represents the darkest brown color, while #10 refers to 10% gray hair. In the same way, #220 refers to the darkest brown color blended with 20% gray hair.

“R” in the color numbers means that the certain color is one shade lighter than the color in front of the ‘R’. For example, 4R means medium brown with one shade lighter.
