Not sure about that
These two screencaps are from the scenes leading up to the climax of the movie. At first I thought that the chrome ones are for hero shots and the blue plasticy ones for stunts but after I watched the movie just for the webshooter bits
I don't know what to think.
I reckon it's blue with chrome on the sides... or maybe they're entirely in chrome and the blue is from the environment HDRI on the CG shots (evening ergo bluish)... or it's chromy blue?
EDIT: Don't know what to believe:
But that clockwork ornament on the webshooter might be a tall order even for HT to make, eh?
EDIT 2: Solved it! It's basically chrome like a wristwatch and then painted blue, which is why under different lighting conditions the chrome might still pop up due to its reflective nature. This pic explains it:
His left hand web shooter looks chrome-ish and yet the one on his right hand looks blue. So, in the end, this is something HT CAN do. Just paint it with the same coat as the eyes, that'll do I reckon.
