It's perfectly legal to change your car's color, but you'll need to go to the DMV and update your registration.Paint job on car?
Your car can be any color that you want it to be. Updating the registration is very important. Reason, a friend of mine had his car impounded, the meter maid thought the plates where off a similar car. The color on the registration was gray and he went to a Perl. Being an under paid city watchmen the idiot never bothered to check the VIN of the car and just had it towed. His excuse was the color was different then what was on the plate information. So PLEASE have the color changed in the DMV computer...
