Wella Colour

Have you ever used the color Wella fresh color semi permanent hair silver 8 / 81 on light blond hair
What was the color as it turned out? there neutralize brassy tones well, and what color did not turn really light blonde hair?

also, just out of curiosity (I know everyone's different) How long did you let on?


Thank you to everyone who can help you!

(Ps serious answers only please!)

Just be careful it is a fairly toner ash if you leave it too long it will go gray
