Ahh. I never even thought of the "tridion" color being the basis of the cars color. I could see how a title might be mistakenly typed up as body panel color if someone was asked what color and one said "red" or "blue" etc.
I know that when a dealer or modern body shop pulls up the VIN it tells all about the vehicle build specs.. colors, trim, options etc. I wasn't sure if there was a letter or number within the VIN one could look at and determine the color (say, S for Silver or B for black.. unless its S for Schwarts and Z for Silver etc, deplending on language used)
