OMG ITS PURPLE W Auburn roots!

😮 :oSo a year ago I had a salon bleach my hair and its was white as white blonde-too much really. I let 12months pass where it was not colored bleached or dyed- until yesterday... I was once a plum red color and wanted to go back to that from the white blonde i had. I also had a year of untouched before root growth-about 4 or so inches at the scalpe was roots. I apply the color and rinse it out and its two colors - auburn red bright almost roots and lilac purple where bleach blonde was before. I am trying to get my current hair iro more of a deep purple tint to it almost that fades to be reddish brown and brown in a few more than 7weeks, to a honey brown. So how do i get the roots and hair the same darker brown red purple color - dark and very not koolaid purple- unless the roots also are purple not red.
