G1 Ratchet in movie colours was awful. Ironhide was cool though because they weren't really his movie colours but his Diaclone colours, which coincidentally resembles his movie colours. Devastator in ROTF colours might work though -- I remember when I first saw pics of ROTF Devastator I thought it kinda resembled Devastator's Diaclone colours in a way... in terms of more realistic colours and also a variety of different colours instead of all being green.
