Help My Color Is Ruined!

Let me start from the beginning.....my natural color is brown but I have always had it highlighted blonde.  I lost my job over a year ago so I couldn't afford to have it profesionally done so I started using SunIn.  Now I already know that this stuff is bad for your hair but I love the blonde color it gave me. My hair started growing out and I couldn't find the sun in anywhere, I heard it had been discontinued but my husband found it at a Biglots and bought it all.  The stuff must have been either old or watered down because it wasn't working too well.  I ran out of that and decided to buy a highlighting kit, the one I bought was Loreal Couleur 82.  It was the lightest shade of Blonde they had.  Ok so you first use the color and then go back and do the highlights.  I knew right off after I did the first step I wasn't going to be very happy...it no longer looked like my lighter shade of blonde but was darker but I figured that I would just put the hightlights all over and that would fix it...wrong!   My hair is no longer blonde but is an ugly light reddish blonde.  I hate it so much!  Is there any product I can use to get the red out or something else to put over it to get the blonde back?

I colored my hair a few days ago....so are you saying that all I need to do is put a toner on it or do I need to recolor and then use a toner?  As far as the ash goes my experience in the past I once ended up with green hair! 

I went to Sallys yesterday and they told me the red will eventually fade?  They gave me stuff to put in my shampoo,  it's a small black tube...  a red/gold corrector.  I haven't tried it yet but I'll post back later after I use it.
