PHP код:

CMD:colorcar(playerid, params[])
{
    new color[2];
    if(sscanf(params,"dD",color[0],color[1]))
    {
        return SendClientMessage(playerid, -1, "USAGE: /colorcar [color1] [color2]");
    }
    new
        string[128];
    format(string, sizeof(string), "You have change the vehicle's color 1 to %d and color 2 to %d!",color[0],color[1]);
    SendClientMessage(playerid, -1, string);
     ChangeVehicleColor(GetPlayerVehicleID(playerid),color[0],color[1]);
     return 1;
} 


change the name or the command to whatever you want, I just showed an example of what I think you wanted.
