I have never ever had this happen before. Guess I have learned a lesson the hard way. The front now has a really dull greyish blue look.
I'VE definitely been there, my suggestion is to wash it again using more color catchers and see if that takes out the extra dye from both sides. I hope you didn't put it in the dryer. Good luck!!
