At home auburn hair tips and help?

I was wondering if anyone would be able to help me. My hair history: I have medium to long length curly thinish brown hair. Naturally my hair has some red shining through. Currently I have honey and light copper high lights through out, but they have grown ou a bit (haven't dyed my hair since July now). Anyways I want to try something new and really would like to try out a copper toned auburn hair colour a la Emma Stone (see pic) So does anyone have any recommendations for at home kits to achieve this colour? I want more copper/warm toned hair rather than the purple-y/burgundy auburns. Let me know your experiences /emoticons/[email protected] 2x" width="20" height="20" />
