Most trains I have seen were grey or colorless to the eye. I have seen 
color in trains only in a few rare instances. One such occasion was 
during Perseid max of last August 97. A -7 fireball flashed leaving a 
persistent train. Initially, the train appeared yellow-orange. This seems 
unusual but the meteor was fairly low near the horizon. Atmospheric haze 
or thin clouds probably caused this color.

Also, during Leonid max of November 96, I saw a few trains with a 
"silvery blue" look. I believe this was simply caused by the intense 
"thickness" of the trains creating an optical illusion. (especially the 
case for the brighter meteors).
