Pure Perfection uses Wella’s slash numbering: 8/0 = level 8, natural reflect.
- Level (2-10): depth, from darkest brown to lightest blonde.
- Reflect: /0 natural, /1 ash, /3 gold, /4 red, /40 copper, /6 violet, /7 brown, /8 pearl.
- Doubled level (44/0, 55/0, 66/0, 77/0, 88/0): the Intense Naturals, with extra pigment load for stubborn grays.
It shares numbering with Koleston Perfect and Color Touch: an 8/0 means the same in all three. With one difference of its own, the /40 copper, which the classic chart does not have.
