[meteorite-list] Bright Streak of Light in Sky Reported fromSouthern Oregon to Seattle

[ks1u]

The thing which is most interesting to me in these fireball sightings is the 
color of the flame.  The only fireball I saw was an orange/yellow.  Is it 
reasonable to make a guess as to the composition based on flame colors, in 
the way geologists do a flame test?  Or, are there too many other variables?
