Question....Uncolor Product..ASAP Please!

Helllo,
I recently prurchased the product called Uncolor by Clariol to remove semi-permanent hair color only ( not permanent Uncolor product, there is two). My question is this....I put a very light blonde permanent hair color on my hair to get it to its lightest point. It was NOT a lightening kit with bleach, it was simply the lightest blonding step before using bleach. It did lighten my hair, but its was a little orangy/strawberry for me, so I then put a semi-permanent toner over it to take it down a notch, which it did. I want to take the semi-permanent color off my hair and was wondering if the Uncolor is going to bring it back to the first blonde permanet hair color I had before putting on the semi-permanent? Or does this Uncolor product turn my hair colors, oh lets say yellow/brassy? Also, I have heard that this produst is pretty gentle on your hair, just was wondering if that is the case?Thanks..
