About those colors you see when you boost up Hue/Sat on the 2004 DVD or Blu-Ray: I don't know what those are about. There was some color variation in the plastic used for the set, yes, but those colors are different than the hues of the actual variance, and oddly distributed. That's simply not what the color variance on the set looked like. Bizarre.
However- this is definitely worth your time to check out:
