Maybe more disgusting than odd, I had an orangish/red 77 D150 that had light blue door panels, dash and seat. It was ordered as a municipal vehicle, but never delivered. I bought it off the original owner in 1993 with 20k miles on it. Even the interior sheetmetal was that awful orange/red color, so it wasn't a repaint and I seriously doubt the guy swapped all the interior bits on it.
