What causes the air to change colors during a storm?

Last night we had a magnificent storm. It’s also been exceptionally hot and hazy here the last few weeks, I’m talking serious humidity. We happened to be sitting outside during last night’s storm and the air around us turned bright pink. I watch EVERY storm that I possibly can (and I have my entire life), and I have never seen anything like it before. Everything had a really intense neon pink glow around us. It was literally as if you could see the air. Beautiful.

Was this just the light traveling all the way down to the ground through the moisture in the air? Is there a name for this phenomenon?
