And now my roots are brighter then the rest of my hair!!
My roots are like light brow kind blonde and my hair is dark brown >.>'
Grrrrrrrrrr ugh I want to put another color , medium copper brown, but if I do then the color would be un even since my roots are lighter!!

Be sure your hair is in super good shape before you color it again. I'd say the reason you see the color difference is because the bottom of your hair was more porous and next to your scalp was more like virgin hair (in much better shape).

You may want to stop at the salon and get an opinion on the health of your hair before you proceed.
