Back in BLACK-Help!

My natural color is mousy blonde/light brown.  Over the last year, I have gone from blonde, to red, to burgundy, to brown, to black.  I got sick of the black and used a color corrector from a beauty supply shop to remove the dye (permanent).  My hair is now a nice copper color, but here's the problem:  No matter what color dye I use (test strands) it ends up back to black!

What is going on, and how do I fix it?  I'd like to go to a dark blonde/light brown shade but no matter what color I attempt, it turns out black.  My hair is shoulder length, cut in a modern shag and I spike the top. 

Any advice?

Thanks, Rebekah!  I appreciate the reply.

How long did you rinse the color remover? Do the color remover again. However, make sure to rinse the color remover out of your hair with warm water for at least ten minutes! This is a very common problem. The dye molecules shrink temporarily in the presence of the color remover. This allows them to be washed out of the hair. If you don't rinse enough, the dye molecules left in there will expand again and visibly darken your hair. Another perhaps more minor point, but still important, is that you want the room to be warm when you use the remover. Thirdly, when you go to redye, use a color two shades lighter than you think you want since your hair will also be more porous, (absorb color more readily), since it has been through much processing.
