A few that come to mind are:
SEA with gray bottom
SEA with wrap around camo
Edwards test birds, mostly white with red or day glo orange high vis panels
QF-4s with various high vis panels, frequently SEA camo top, but gloss finish instead of flat. Tyndall has at least two of these they send to airshows that are pristine & immaculate.
Airframe #12-200 was the prototype for the C, D, E, RF and fly by wire Phantoms. One interation of this bird had canards on the air intake trunks. Beautiful white paint job with blue stripes down the side and dark blue belly, leading edges and stab tips. It is at the USAF museum in Dayton now. Micro Scale has a sheet with these marks in 1/72.
