Hard to tell from digital pics of course but kinda think if it is resprayed any of the original colors it's the Luxury Rich Red. Nothing there looks dark enough to be the midnight red. The LuxRich is a good color though.
All the solid color parts are easily sprayed and the codes for Midnight Red and Luxury Rich Red are available. So the solid parts aren't a great problem to do should you ever decide to. The others, however, could be tough to find or Expensive to get done.
Not suggesting you are, but in case you might be interested there is a listing currently on the site from a guy selling classic red SERG painted parts that were his spares. Check it out at this link if interested:
