Hi, I'm a mobile hairdresser been on my lonesome for 6 years but have 10 years previous salon experience I need help deciding on a shade of time for my clients roots for her balayage, shes naturally a base 6 and I usually use 5.0 with 4% peroxide. The photo she has sent me I see a different colour every time I look at it. I was thinking mood, 4.6 and I also use wella....open to any suggestions, thank you kindly xx
