On my copy (Rhino, excellent condition), the soldiers in that particular shot are in greenish brown uniforms. I believe the lighter outfits in that facility are worn by scientists (see Vernee Watson Johnson's credit), and the Baroness poses as one of them.

More similar to Starduster are the paratroopers seen in Battle for the Train of Gold and Money to Burn. They wore light blue flight suits with a white helmet and straps, and white parachute packs and breath masks.

The real animated Starduster can be seen at the very end of the G. I. Joe Action Stars cereal commercial, which also featured Duke, a Cobra Officer, and a live-action child. The commercial is (or at least used to be) at Quick Kick's Theatre.
