REDKEN shades advice pa-lease !

I have dark ash brown, light brown hair that has been treated with mostly color but it always turns out black looking! I went to the Aveda school students so whatever :(

I have gotten 2 sets of highlights that have turned my hair looking like my natural color with alot of gold (I assume undertones showing now that i have my hair lightened). I look plain & old like this & I want to be a young multi-faceted hottie.

I want to use REDKEN shades to obtain this color below--any advice,, I will be going to a pro but Im a color-nut & want some know-how before I just go on a whim!
Thank you sooo!!!
