Coloring hair, gone wrong.

So I had like a light brown almost copper hair color that I liked. I wanted some highlights tho. My sister who is in cosmo did them for me and they were horrible. They were patchy, not like the photo at all, and just horrible. She told me she could do it but it ended up bad. So I decided to get some light copper hair and brown dye. The orange was to bring back some red tones so that it wouldn't look green after putting the brown in. Anyways the orange was WAY too red. Now the brown looks like black in some places and red in other places. I hate it but I can't do anything about it now.
