Yeah I was about to post the same thing. Except, I'd say the casements in the film are definitely orange, not brown, right?
Regarding the hat, I presume they will use a technique to create the satin/velvety look that is used in some toys. They spray some kind of paint/particle mixture onto plastic or metal, and it dries to the desired finish. Of course, I have no idea how that would stand up to rain and humidity. I'm also curious about his arm. Are they going to go with fabric as it clearly is in the movie?
