I don't think bleach does much, I'm sure the idea has been hatched before.I'm not much into dyeing and such so if I sound stupid it's because I am and not trolling but have you tried bleach?
I've never done it or even know if it would work but an idea coming to my head after midnight.
That might work. Good idea.what if u just dip the back side, so it will be dyed red on the underside but still be yellow plastic on the top, so it will kind of create a orange???? maybe ???
But I got some orange RIT last night so I think I'll just try that.
