Meteor color is determined by heat produced, not, content.
The hotter it is, the closer to blue it gets. Most meteors look white because they aren’t bright enough to activate the color sensors in your eye. Back in 1999, when the Leonids did their 33 year peak, most all that I saw were green. I have also seen Orange, Red and Blue.
Unless this was after midnight, it was probably just a sporadic hunk of rock or iron burning up.
Ah, so content has no effect on color, just heat.
Not buying that.
The one *good* one I saw, had predominantly green sparkles in the tail, but there were bluish white and white intermixed with them.
Also by tail, I mean there were two tails.
As explained to me by another Freeper, the tail straight behind it was from debris coming directly off of it, the second tail, that seemed to hang too close like a horse's tail, were objects that broke off earlier that were actually flying in formation with it and burning up as they entered the atmosphere along with the main object.
The *head* of it (main object) was an orange/white color.
If your statement was totally right, should not the color have been uniform because of the relatively close proximity of all objects at the same heat/speed?
Plus had too many chemistry classes and labs that I know one of the first things you do with an unknown sample, is to take a small drop and put it in the flame of a Bunsen burner to see what color/colors appear.
Not a perfect test, but a good start at determining further test.
