How to neutralize colours

If you want to change the colour of hair, you need to know all about colour neutralization. Take a look at Figure C (tertiary colours), and see which colours influence each other. The colours that are opposite to each other, neutralize each other. The importance of this knowledge is, for example, shown by hair bleaching. Every shade can require another ‘correction colour’ (see correction chart).
