A vehicle body colour change is a statutory sub-category of motor vehicle alteration registration. It refers to the official administrative procedure where vehicle owners modify their car's exterior paintwork for personal styling or commercial purposes—without compromising structural integrity or safety—and subsequently register the change with the relevant traffic management authorities (Vehicle Administration Office) in accordance with the law.

While car owners are entitled to personalise their vehicle's exterior finish, strict legal boundaries must be observed to maintain public order, ensure road safety, and facilitate law enforcement and accident investigations:
Prohibition of emergency vehicle liveries: It is strictly prohibited to respray, wrap, or apply exclusive colours, insignias, and livery patterns that are identical or strikingly similar to official emergency vehicles, such as police cars, fire engines, ambulances, and rescue vehicles.
Visual safety and reflectivity standards: The altered colour must not cause severe visual distraction or glare to other road users (e.g., highly reflective or blinding chrome finishes must be evaluated carefully to comply with local regulations). In addition, factory retro-reflective markings and functional lighting areas must not be obstructed or altered without authorisation.
Under current motor vehicle registration regulations, a convenient "modify first, declare later" policy is in place (allowing car owners to complete the respray or vinyl wrap before submitting the update to the transport authorities within the stipulated timeframe):
Physical vehicle inspection and VIN verification: The owner presents the completed vehicle at the inspection bay of the Vehicle Administration Office. Authorised personnel will photograph the exterior, cross-check the chassis number (VIN), and confirm that the body colour matches the application with no unauthorised modifications present.
Document submission: Submit the owner's original identification document, the Motor Vehicle Registration Certificate (original logbook/grant), and the Motor Vehicle Licence.
Record endorsement and document reissuance: Upon verification and approval, the authorities will endorse the alteration on the Motor Vehicle Registration Certificate and issue an updated Motor Vehicle Licence on the spot (with the vehicle photo updated to reflect the new exterior colour).
Wrap material specifications: With advances in automotive wrapping technology, many car owners now opt for colour change vinyl wraps (such as matte, gloss, or gradient finishes) instead of traditional respraying. Vinyl wraps are equally subject to colour modification endorsement regulations. If the wrapped area exceeds a specified proportion of the total body surface (typically over 30%), it must be legally declared.
Roadworthiness inspections and on-road compliance: Vehicles that fail to register their updated body colour within the designated timeframe will fail periodic technical inspections or roadside enforcement checks due to discrepancies between the registered vehicle document and the actual vehicle, and may be subject to administrative fines and penalties.
Changing vehicle body colour is a popular and legitimate avenue for car owners to showcase their individuality. By completing the official registration process, owners can give their cars a fresh new look while ensuring transport records remain fully aligned with the actual exterior, upholding road safety and traffic regulation standards.
