When the vehicle's green book is mortgaged, a color change is not permitted. Only after the mortgage loan is fully repaid can the color change registration be filed. According to the "Road Traffic Safety Law," the following documents are required to apply for a change in the vehicle's body color: Original "Motor Vehicle Change Registration Application Form." Original and photocopies of the identity documents of the vehicle owner and agent. Original motor vehicle registration certificate. Original motor vehicle license. If the color change area does not exceed 30% of the vehicle's surface, no change registration is required. Conversely, if it exceeds 30%, the change must be registered and filed within 10 days after the color change. Notes on Vehicle Color Change: Before changing the vehicle's color, consult the local vehicle management office where the vehicle is registered to confirm whether the region allows color changes using wraps. If the region does not permit this method, the change cannot be registered, and the wrap must be removed to restore the original color. Additionally, according to the "Motor Vehicle Registration Regulations," owners are no longer required to apply to the vehicle management office in advance. They can first change the vehicle color, install body kits, replace the engine, etc., and then apply for change registration. According to Article 10, registered motor vehicles must apply for change registration under the following circumstances: Change of body color. Replacement of the engine. Replacement of the body or frame. Whole vehicle replacement due to quality issues. Change of use, such as converting a commercial vehicle to a non-commercial vehicle or vice versa. The vehicle owner's residence moves in or out of the jurisdiction of the vehicle management office. Furthermore, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": Police cars, fire trucks, ambulances, and engineering rescue vehicles must display designated markings and install alarms and signal lights as required. Other vehicles are prohibited from using similar markings, alarms, or signal lights. According to Article 56 of the "Motor Vehicle Registration Regulations," failure to register a color change as required may result in a warning or fine from the traffic management department. The vehicle may also be impounded and required to revert to the original color.
