Should I do it?

[HungryClocksGoBackFourSeconds]

So I used a colour remover on my dark red hair, and I am surprised that it actually worked.

My natural colour is a dirty blonde/light brown and it is currently a light brown/auburn colour. It's actually quite nice, but I want to put some blonde on it, I'm just a bit nervous.

I want to get back to close to my natural colour because I'm getting tired of dying it all the time and I actually quite like my natural colour, I also don't know how I would be able to keep the current auburn shade up because I haven't actually used a dye to get to it.
I'm worried if I stick the blonde on, it might go lighter but still have some red in and come out a strange orangey yellow colour. What do you reckon? Worth the risk or not?
