I was surprised in the beginning that they made TFilm Ratchet a greenish color (lime green-dark green). At first I didn’t think it fit him; Ironhide was black and that made him look hardcore, but Ratchet was more different than I thought he should have been. I was hoping he would be recoloured white/red, as such: http://tfwiki.net/w2/images2/d/d6/Movie_Voyager_RescueRatchet.jpg http://tfwiki.net/w2/images2/8/8b/TSRescueRatchet.jpg But now I don’t mind it so much. I think it in some strange way suits him well: green is a militant color after all (befitting an army medic as Ratchet), and green is also connected with nature, specifically of the planet Earth (as a medic, Ratchet is devoted to preserving life). But I have to say they got the shade right only in DOTM, in the first two films he looked like he had jaundice.
