Some will dye, others won't. I have a set of previously blue Hutch grips that are now perfectly black after being dyed. I believe some oakley grips can be dyed too. I would have thought that Tange grips would dye, seeing as they're from the same moulds as Hutch grips, so possibly made of the same material. On the minus side, i ruined as set of Ame bubble font rounds bu trying to dye them. Should have done a thorough search on the subject beforehand
