The material appears to be closer to the ESB color, with the ROTJ color needing to be lightened (although I think the color of the MoM vest is a good deal lighter than we see in ROTJ), possibly due to laundering prior to setting the exhibit or it's use in the SE's.
TD-I saw that thread but they mentioned that the color was for ROTJ, since the ESB is darker and may not take die to well. then later in the thread they make it sound like the opposite.(i'm so confused :confused)
Yes, the neck and material on the fingers is believed to be the same as the vest.
Oh, and one more thing. is the neck seal and the white on the gloves the same material? I saw that they were discussing it and thought that it was, but i wasn't sure.
