Vehicle default colors
This file is copied from the MTA:DM Server.
File Name: vehiclecolors.conf
File Location: <MTAPath>\server\mods\deathmatch
This file defines the color combinations a vehicle can have.
[Vehicle ID] [Color 1] [Color 2] [Color 3] [Color 4]
Note that most vehicles don't need more than two colors. You can specify a vehicle ID more than once to specify more than one combination for a vehicle. The color combination used for a vehicle is randomly decided each time a player spawns in a vehicle.
If you mess this file up, just delete it and the server will generate a new file with GTA's default values in it.
In this example, vehicle ID 445 is being set colors for the server to use when the vehicle is created, you can add your own by adding new ones under it or anywhere inside this file as long as the syntax follows the example above.
