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.
The content can help determine heat, different contents burn differently and burn different colors. We learn this in middle school science lab by putting things over a Bunsen burner.
For what it is worth, the article in the Wikipedia does say that meteors get their color for chemistry AND/or the amount of heat.
I had always been told it was just the heat, so, I learned something new.
I normally am cautious of wikipedia articles, but, this one does have a good bibliography, so, I will say it is ok for this information.
