Back in 1999 when I painted my Boba suit, I used Krylon Farm & Implement John Deere Yellow (1816) for the shoulders and knees. It looks brighter yellow on the spraypaint can cap, but it actually dries more of a yellow/orange like the Boba parts are. I still have those parts around and today am comparing them to the reference pics.....sitting next to the computer holding a shoulder bell.
Now, Rogue Studios hadn't made the master paint list by that time and there weren't the reference CDs around either. I'm looking at the first Boba reference CD at the AOSW exhibit (CKING's pics) and that spraypaint I used is practically dead on to the AOSW shoulders and knees. (Yeah I know there's a pre-pro knee thrown in there, but I mean the ROTJ knee).
So instead of mixing the Reefer Yellow and UP Armor Yellow together as the Rogue Studios list recommends, this may be a quick alternative for those who are "airbrush challenged". But, since the spraypaint I used was back in 1999, I don't know if the company has changed the consistancy of the color with the new paints, but my shoulder bell appears to be 99.9% the exact same base color as the AOSW exhibit pics I'm looking at.
For the ROTJ shoulders/knees, I know most guys mist them with an orange tone in spots and that's fine. Just sharing my quick base color with you all who are interested in creating the AOSW "Special Edition" style suits. 
The M.O.M. shoulders/knees appear a tad different color than the AOSW knees, but that's most likely the lighting change between exhibits.
