Dan,
Thanks for the explanation, but I was really looking forward to doing some
recreational calculus this morning.
All of the good photographs of the great 2001 Leonid meteor shower showed a
progression of colors from green at the beginning through magenta at the end.
Here's an example by Tony Hallas:

As the meteors go deeper into the atmosphere, their colors shift toward the
red. Has anybody done an analysis to determine which elements those colors
represent? Or is the atmosphere's composition about the same throughout, and
it's just caused by different temperatures and pressures?
Tom
