Wunderbar colour

[KellyS13]

Hi Has anyone used 3% peroxide to cover grey roots with Wunderbar Base 9? If so did it cover well? I used 6% last time & it didn't cover 100%
I'm new to this brand as I used to use Rusk but they've been discontinued

What shade are you using. I'm wella trained, and the colour theory is the same as wunderbar, and I've used it myself so should be able to help.
