Largely its for thermal protection. White reflects more of the sun, keeping the aircraft cooler sitting on the tarmac. (So why not leave the aircraft unpainted metal like American used to in the 80s?) Airplanes fly high enough you are marginally more exposed to radiation from the sun.

The Short Answer

Largely its for thermal protection. White reflects more of the sun, keeping the aircraft cooler sitting on the tarmac. (So why not leave the aircraft unpainted metal like American used to in the 80s?) Airplanes fly high enough you are marginally more exposed to radiation from the sun. Having a coat of paint protects against that. Also, lighter colours make it easier to see stress fractures or leaking fluids.
