ELI5: Why does the sky turn green when there is a very high chance of Tornadoes?

Living in the Mid-West, I’ve noticed the sky, clouds, and the air in general all pick up a green hue, and it gets greener as the likelihood of a tornado rises. Why?

The "greenage" or green color in storms does not mean a tornado is coming. The green color does signify the storm is severe though. The color is from the water droplets suspended in the storm, absorbing red sunlight and radiating green frequencies.
