The equipment yellow would be CLOSE to ROTJ's color....
Zenix...keep in mind the yellow outlines on the green armor is brushed on....to be accurate you might want to consider that....I would spray that paint into the cap of the paint and brush it on myself....
As far as the color....I think huntclub is close to the ROTJ color....but theres ALOT of misting on the armor.
The hunter green is very GREEN...I used to use it for the back of the ROTJ helmet when I used rattle cans.
Theres a satin strawflower color I used for the knees and shoulders outlining....again those are brushed on, on the real suit.
Youll need to mist black on the green armor pieces over the top of all other weathering....which theres lots of different shades of green on there... experiment with things but try not to mix rusto and krylon or you might end up with mush....as they don't get along
