On white/grey hair this Natural Brown shade is likely to be a warm light blonde to light brown colour. On dark blonde hair it is likely to be a warm light brown. On light brown hair it is likely to be a warm medium brown.

A darker colour result may be obtained by repeated applications. The longevity of the Natural Brown shade depends how porous your hair is and how often you wash it. It tends to last on average about 3 to 4 weeks on the roots, but it can become permanent on porous areas of your hair such as the older, longer lengths of hair which become more weathered and porous over time. On very light-coloured or light grey hair it sometimes appears to have a green tinge at first, but don’t panic - this will fade gradually over a few hours or days, as the dye oxidises and the colour deepens. The colour is also affected by how long you leave the paste on. If you leave the paste on for 1 hour it will be a lot lighter than if you leave it on for 3 hours.
