Spawn color addon car?

hi

how to do it so that the vehicle addons spawn always in the same color example black.setting in the vehicle files "carcol, handling, ect ect or in the scripts?because for some of my gangs I want to give them a unique color. For example, mercedes G65 in white for cartel. I have succeeded because I modify the template of the vehicle.

That would be in carvariations.meta
