any suggestions? salon made golden blonde white

I was born blonde and with help have stayed blonde. Always just the one step coloring.  Returned to the salon for root touch up and ended up with gold roots but extremely light/whitish ends.  Beautician used a cool shade (I don't know why she changed...didn't ask me) and I don't like the ultra light color.  Her suggestion was to give it a few shampoos and it will "fade" and blend.  Is there any toner or color I could apply to put more of a golden blonde hue to the hair?  My hair is in good condition, never permed, but below my shoulders. 

In the past I had colored my hair at home with a shampoo in color.  Had been going to a salon for the last several months due to shoulder problems.  Normally just the roots were touched up (brought up to the blonde color).  My roots are a level seven.  This time she put the color on the roots and "refreshed" the ends for about 10 minutes.  But this time she used a cool blonde shade (it was a number and I don't remember) instead of a neutral shade so now the overall color is very very light, whitish blonde but some gold still at the roots.  I told her I thought the color was too light and too white and she said to just wash and condition it and it should blend.  I just wanted a soft golden blonde color....not beach baby blonde.
