Throw it back in the washing machine with a color catcher, rewash and than dry. If you dried it on low heat it may not have set. But do that before anything else. Once you start with other things you are setting it harder. This advice comes from a fabric expert I know. (Not me, she is my go to person!)
Edit: The Bleedout might be the trick also but I would try just a color catcher first, just my thought. Good luck and let us know what worked.
