Yeah, the shoulder w/ the bantha skull is definately a lighter and duller yellow. The other one looks like its the same color as the knees, except its really dirtied up. I used caterpillar yellow for my knees & right shoulder, but theres most likely a more accurate color to use...I'm not shure exactly what that is, but the colors Lee suggested are probably a safe bet as being the right choice.
Well we painted ours but we don't like the color and it needs to be repainted. :facepalm
This thread is for the AoSW costume but I'm sure the colors are fairly similar. The first post has all the different floquil paints used on the real suit. http://tdh.prop-planet.com/viewtopic.php?topic=6556&forum=2
