What to do?

About a year ago I had my hair bleached blonde and ever since I would just keep touching up the roots and my hair kept getting lighter. It was such a nice colour and it was soooooo hard to get!

 

I got a little tried of having to dye it all the time so I want to go back to my natural hair colour (Dirty Blonde) but what happend was it turned green! So I paniced and decided to go for blue black thinking you can't go wrong with black but my hair ended up going all blue, because my hair was so light before so about a week later I dyed it all black. Now I dunno what to do my hair is black and starting to fade a bit....and I really don't like it.

 

I know it would take a while to get back to my blonde but is there anyway I can fix it so it's a least a dark or light brown before going blonde. I don't what to have to wait for my hair to grow out it will look sooooo bad!!!

 

Please help.
