Hair colour spectrum in hairdressing

Colour theory is basically the colour spectrum.

There are terms that we don’t use in everyday life.

E.g.: for green – matt

         for blue – ash

         for violet - pearl

While bleaching, there might remain yellow (gold), orange (copper) and red shades in the hair. You can neutralize it by applying the directly opposite colour.

For example you can neutralize yellow (gold) shade by violet (pearl).

Orange (copper) can be neutralized by blue and red by green (matt).
