There is a product called Carbona Color Run Remover. I'm not sure if you can get it in stores anymore but you can order it on soap.com (amazon may have it also). I usually get my orders pretty fast from them. I haven't tried this particular product but I use the other Carbona stain removers and they work great. You might can try a fabric store for some kind of dye remover also.
I know how you feel, my daughter just got permanent marker on one of her good shirts!
Hope this helps! Good luck!
