confused about how to correct orange tones

hello
just registered here. I need some help witht the orange hair thing. I just got my hair dyed for the first time. My natural hair color is dark-medium brown and i was going for a light brown to dark blonde. So i went to my hair stylist and i told her what i wanted and we looked through the hair swatches and picked one out. But my hair looks nothing like the sample. It turned out a orangy brown. So how do i fix this? Do i need a toner in a purple-blue or green? Or i heard something about a ashy blonde color? So does that mean i need to get it dye an ashy blonde over my orange?Or do i need to start all over and get it bleached first before the color which prevents the orange tones? I would love it if all i need was a toner to put on for 15 min or so that would remove the orange. I am going to go to a salon and have it done not try it myself. But i don`t know if i should go to my regular stylist i have had for 4 years or go somewhere else and ask for a color specialist. Since i am somewhat annoyed that she didn`t prevent this from happening in the first place. I want to prevent damaging my hair so would like the gentler option if any. Please advice. thanks amberw
