Redken EQ and color ?

Please give more information.  A level 4-5, ash, warm, in between?  Is this your natural color with orange highlights?  What exactly has been done to your hair?

It is very warm on the top layer and more in between on the underneath layer.  My hair was professionally highlighted for years,  then 2 years ago i made the mistake of using color experte 8.0.  I let it grow out for a year and have been using 6n demi (clairol) and sometimes a little 6w (wella) which is too orange.  The 6n goes on very dark (and wrong for my coloring) and washes out quickly.  I tried 5n perm on the bangs only and it was too dark.  I used colorfix twice last week and now i have orange bangs and the rest is reddish/light brown.  In the sun it almost looks strawberry blonde!  My hair really pulls red so I want to tone the red down. and bring the base up a level.   As you can surmise, I am a real amateur but I am trying to read as much as possible.

Thank you for your help!!
