Some old-tyme colors (Orange) I have not personally seen other than an OIC that was Huey pilot with VC-6 in Antarctica before they decommed and he became an HSL guy.
That would be VXE-6, who wore orange for the obvious reason that it stood out in Antartica. We had a few former LC-130 guys in my squadron.

VC-6 are the guys that fly UAV's.
