How do I remove plastic-based dye from my hands?

I spent the last several hours making plastic molds of barbie heads in various colors for my sculpture class, and the dye I was using is plastic based (because if it was anything else-based it wouldn’t let the plastic cure/harden). I was really careful about wearing gloves until the last one, when I covered both of my hands in the thick green dye. Am I destined forever to be hand-zilla, or is there a way to get this crap off?
(Of course I’ve tried various types of soaps and hot water (including gojo) and it hasn’t helped. Also, my hands are all weird and filmy.) :(
