My wife heard something on the radio about how you could judge the quality (or maybe the expense) of a fireworks show by how much blue was included.
I noticed that, in our town's fireworks show (which is never very good, but still fun to watch with a beer in hand from my back yard), there was virtu ally no pure blue. There were various shades of purple and some bluish whit e, but I think I only saw one single pure blue burst.
I also watch the NY and DC shows on TV. While they did have some blue, ther e was not nearly as much as there was of the other colors.
So what's the deal with that?
