/v [id] colour

[TEF]

As far as I know, the first color ID that you put in is the interior's color and the second is the exterior's color. For example, "/v [ID] color 0 1" would make the car's interior black and the exterior white (if you had a car with interior color settings). If there is no interior option for the car you are driving, simply put any color ID for the first and then what color you want as the second. You simply need to remember to fill in both color IDs. There is no bug here.
