And BTW, the color of the helmet DOES NOT match the armor colors. The only color that could get close is the Spruce Green, but it's lightly misted with flat black and probably a darker green...bottom line, is darker than the green in the helmet, specially the ROTJ helmet (actually the MoM pics)...just ask Tylerdurden and you'll see...he's the one who told me that.
