Ilumina Wella colouring advice?

[Shally]

Hi,
I’m currently working With a client, with 40% grey, root colour 5/81, with 6% developer. She wants to go go a shade lighter mid to ends to a chocolate brown, I was thinking of using60% 5/81 and mixing 40% of 7/81 With 9% developer. Her base is a 5.
any advice would be appreciated.
thanks

Yes that would work, but obviously you're going lighter on the base and giving it an extra level of lift with upping the developer so you may find you need to add a bit more tone

Thanks Ron,
So up the 7/81, she has underlying red tones so want to bring out the yellow gold in her hair..
50/50 split of 5/81 and 7/81 with 9% developer
