What do the numbers of a hair color mean
There is a pretty simple explanation for this! It tells you which color pigments the color contains. The numbers are the “name” of the colors, and the order indicates the amount.
We have learned that the pitch is a number between 1 and 10. We have also put numbers on the shade the color contains. This is to show which pigments the color is made up of. If you want to neutralize yellow, you must use a color that contains .2, if you then use a color that only contains .1, this can become green. Then yellow + blue = Green.

1 = Blue💙
2 = Purple💜
3 = Golden/yellow💛
4 = Copper/orange🧡
6 = Red❤️
7 = Matte/green💚
8 = Chocolate Combination with hot and cold🤎
The first number is the pitch of the color. The numbers after the dot tell which reflexes it contains. The first number after the dot is called the primary reflex, this is the most of it and the number no. 2 after the dot is called the secondary reflex and this is the least of it. So the name of this color would then be: Very light blonde, with main reflex of purple and with a little blue. There may be some differences between the different suppliers.
