Getting your car painted in the same colour is allowed. If you are planning on changing the colour it needs to go for a pre-approval from RTO. This is done to reduce criminal offences which can be covered up by painting a car in a different colour.
Also one can get their car wrapped in any colour without any RTO approval or permission. This will keep the car’s original paint intact and prevent it from damage from the sun and small stones that might chip the paint.

Structural Changes

No structural changes are allowed on any vehicle. If you want to extensively modify the structure of the car you need permissions from the ARAI and these are not easy to get. Here you need to give a legitimate reason for the modification and after that, the car doesn’t necessarily get road-legal status.
