Wella to tigi colour

[rachy86]

Hi guys,
One of my outside of work clients(friend of a friend)wants my hair colour which is 5/75 in wella koleston,she wants me to use TIGI colour though as it is the only colour which doesnt have the minor ingredient she is allergic to.
My question is can anyone advise me on which colour that could be in TIGI?
Many thanks

if u ask me in a week i will be able to tell u, we jus started using it today but i aint in till the weekend, jus had the theory . . . but DONT use 4/75 in tigi because there 7 and wellas 7 are the complete opposite of eachother lol

i dont even have a colour chart to help u or i wud have xx

I know learning all the new tones a nightmare i have a terrible memory.
Perhaps give tigi a call so they can explain their tones to u so then u can work our the colour to match.
