They all had subtle hints of color, but did anyone else notice that Grimlock seemed to have green highlights? I thought I was mistaken but after seeing it again, I think he's green - anyone else notice this?
Scorn also had red Strafe also had blue I tried looking to see if Slug had purple couldn't see any though.
there's really good images of them in their robot modes over at tfwiki.net if you're interested...the dinobots...gosh that scene really got me the 2nd time through....dinos were def not useless....galvatron's forces win if not for the intervention of the dinos
Ok, I was just assuming he'd have gold based on the toys, but the green just surprised me. Have to go check the TFWiki link - thanks!
The green highlights might be some kind of patina (like what you find on bronze statues) he developed on his chassis over time.
I've been thinking Grimlock had some green coloring since the early trailers. The japanese 'black knight Grimlock' leader class toy seems to be adding quite a bit of a greenish blue tint.
