Which color to do?

Hello I posted earlier about my hair which is a silver/grey color. I thought it looked good on the model earlier and most of you said it looked great on the model. Most of you said it looked exactly like the pic. They did do a good job matching. At the salon they asked if I liked the color it looked great but after coming home for a while I don’t think the color suits me. I already paid a lot of money. Should I ask for another app and how should I ask? I don’t think I like this silver/grey color it doesn’t really suit me. Also I had a lot of split end. Natural hair is black and I don’t like the black anymore should I go with the brownish color?

Please no negativity I know I made a mistake.
