What leads to transformer explosions emitting the colors they do? (i.e. green or blue vs red)

Here in NYC, the sky was glowing a light bluish color 4 hours after sunset when a transformer blew up in a nearby neighborhood.

It comes down to the chemistry involved in the oil in the transformer, and the electrical arcing you get when it happens

We have been conditioned to think all explosions are yellow/Orange/red by movies, when in the real world they aren't. In the movies they use gasoline, propane, and other hydrocarbons to produce the fireballs we see. They're relatively low velocity, and visually spectacular, so perfect for filming.
