Rangerover classic colours?

The o/s/f door on my 93 classic is a slightly different colour to the rest of the car,this annoys me as apart from the colour difference its also got a nice crease down it where the door opened too far and caught the wing (previous owner and the checkstraps now been replaced).Anyway my Rangerover is plymouth blue and i think i know for a replacement locally but was wondering if there was another colour blue close to plymouth as i don't want to get another replacement in the wrong colour or could it just be the door fitted has been re-sprayed at some time.I know the door is not origanal to the vehicle.

All you need do is get hold of another door regardless of colour, and spray it in the correct colour to your original, take the door inner panel off and snap it into the new door job done

I know what your saying and it is easy enough to swap doors but seeing the 2 different blues made me wonder how may colour variations were on the classic.I will go and get the blue one on the weekend anyway.
