Suggestions for Neutralizing Red/Orange

So, this is what I did to my hair last night.

Some background, my natural haircolor is about a level 4 with a lot of yellow based red/orange.  I'd been having my color professionally done by a great colorist, lightening to about a level 7/8 then toning (partial) to a very pretty shade I can only describe as rose gold about a level 6 after toning, a light to medium cool (rather than warm) copper tone with a very slight violet undertone. 

I could no longer afford to have it done professionally so bought a bunch of Redken supplies and decided to do it myself.  I lifted large haphazard chunks to a level 8/9 with Blond Icing (ammonia formula), then used shades EQ two parts 7G, one part 7CB and one part 5C. 

I actually think it turned out rather pretty, but it's WAY darker and far more red/orange than I wanted, it's a bit deeper and brighter than it appears in the pic, really a very bright true warm copper.

I'm sure it is going to fade fast being red and a demi, and I'm concerned it's going to be very brassy when it does. 

So my question is, will I need to bleach again to get back to a lighter shade or should it fade sufficiently?  My hair is in very good condition and can take a lot of damage, it can def take another round or two of bleach at this point if I have to.  Alternately should I perhaps use a color remover instead and then re-tone?  And lastly, would it be possible to just apply another glaze to tone this down? I'd like to remove some of the heat but also don't want to go ashy and muddy. 

If you're not wanting to go extremely light don't strip the color out!!! You can put a color over this but I would use a 30 volume developer to help lift and process the color more. I've never personally used Redkin so I don't have any help for you with those colors. But I do know that a no ammonia dye won't lift very well. I would suggest mixing an Ash & a Neutral of the same level together to tame down the red color you have. I noticed you used a Golden and 2 Ash tones. So stay away from the G. If you really want to get rid of the red then use only an ash anything that had a Blue, Violet or Green base will do. If you want to just add an other glaze over it then try an ash and also use a one level higher than you really want to get the color you want cause ashes do come out a bit darker. Good Luck
