/cgl/ - Cosplay & EGL

Pls make my dream come true anon.
Ok so this is what I've planned out with my research, tell me if any of this sounds retarded before I actually go do it.
> Want my hair a washed out Taro, pic related.
> Hair colour currently: Dark Brown
> Hair length: Hips, butt length when uncurled

I assume I'll need buckets of toner for this yes, but how light should my hair go to achieve this? I can't tell if this is a light brown or it transcends into dark blonde, with some obscure reddish purple dye???? And once I reach either the light brown/dark blonde stage, I can apply some weakass purple dye right?

I have more pictures of this model and her glorious hair colour if it helps to see in another light what I'm aiming for
