Blue in most jurisdictions is reserved for the police. Police are red-white-blue but often just red-blue, fire/ambulance are red/white and service vehicles are yellow.

I wonder if anyone here knows what purple lights are reserved for? A purple light on a car is thing all drivers are meant to know.

Apparently for anything, from funeral service to escorting oversized vehicles to HAZMAT response to whatever you feel like - depending on which country you live in :).
